Good morning, My phone's earpiece is bad. I can only hear when it is on speaker or when I use an external earpiece. How do I fix this and how long will it take? Redmi note 7 pro |

Mrshape: I cannot believe that you would be the one to share something like this that defies logic. Anyway, If you write a computer program for this, You will get 2,302 words that will add up to exactly 100 Amongst those words, a whole lot will not be positive E. G The word CRUDITY C+R+U+D+I+T+Y 3+18+21+4+9+20+25 = 100% Should we start being crude because CRUDITY adds up to 100%? 6 Likes |

The defence is not only stewpid but foolish So, if you procure wheelbarrows for works, you will commission the wheelbarrow? Establishments that usually procure heavy equipment do not even put a tape round it for commissioning talk more of wheelbarrows. This is the worst damage control in history. The idiota that was hired to do this damage control should be fired. 24 Likes 1 Share |

Jodha:Yes now. Check your solution. Your base is even wrong. Your denominator is supposed to be 2 x - 5/2 and not 2 x 10. |
Education / Re: A Good Mathematician Is Needed To Solve This Plsssss by naturalwaves: 6:28pm On Jan 07, 2020 |
Jodha:It is not different. It is the same thing dear. Simplify the answers gotten from the quadratic. It is same as what I got. 2(1+2 root 6i)/5, or 2(1-2root6i)/5 0.4(1+2root 6i), 0.4(1-2root6i) 0.4 +1.96i or 0.4-1.96i Did you see that it is the same thing now? The method is very very reliable. If you know who Po-Shen Lo is, you wouldn't even say the method isn't reliable. |
Education / Re: A Good Mathematician Is Needed To Solve This Plsssss by naturalwaves: 6:16pm On Jan 07, 2020 |
Jodha:I have edited my comment to come with solution. Look up, you will see it. Better still, let me repaste the quadratic solution again.

Education / Re: A Good Mathematician Is Needed To Solve This Plsssss by naturalwaves: 5:56pm On Jan 07, 2020 |
Jodha:The solution is not correct dear. How do you find the square root of a negative number? There must be a complex number in your solution but there is none. You should get the exact thing I have below when you use quadratic formula. Note that the answer given here is same as what I got when I used Loh's methods.

Education / Re: A Good Mathematician Is Needed To Solve This Plsssss by naturalwaves: 1:13pm On Jan 07, 2020 |
Jodha:Okay, Let me try this, Multiply through by 2 and modify equation to obtain, 5x2 -4x +20=0 Observe that the coefficient of x2 is not 1 So, divide through by 5 to get, X2- (4/5)X + 4= 0 Using Loh's theorem, Half way through 4/5 is 0.4 Hence, ( 0.4+u)(0.4-u)=4 0.16- u2=4 u2= -3.84 u= square root of (-3.84) u= square root of [(3.84)(-1)] u= 1.96i (Note: In complex number, square root of -1= i) Our answers are (0.4+1.96i) and (0.4-1.96i) As for De Moivre's theorem, let me give you one of the videos from Eddie Woo. He takes his time to explain concepts. Check through some of his other videos. He is a good teacher. https://www.youtube.com/watch?v=Qha-Lsdj5xo |

Jodha:Give any example of a quadratic equation that is not in that form. Let me solve it using that method. Preferably, give one whose coefficient of X² is not 1. |
Education / Re: A Good Mathematician Is Needed To Solve This Plsssss by naturalwaves: 10:36pm On Jan 06, 2020 |
enawt:Yeah sure but this method works well for a wide range because of that middle interval method. The method is basically for secondary school students but still works fine for even decimal answers that an ordinary factorisation method would not solve. |

enawt: It isn't complex. The idea behind this method was to stop that process of guessing for factors and doing trial and error in the case of factorisation method. https://www.youtube.com/watch?v=ZBalWWHYFQc&t=4s |

enawt:Sobo ke? Lmao The entire methods for solving quadratic are all related. It is a faster approach for teaching students particularly if the coefficient of X is an even number, it can be solved in less than 30 seconds. You also need to make sure that the coefficient of X² is 1 before you start @Jodha |
Education / Re: A Good Mathematician Is Needed To Solve This Plsssss by naturalwaves: 9:56pm On Jan 06, 2020 |
Jodha:It has not be named yet. However, it is a derivative of some old Babylonia method, Viata's formulas, Greek and French approaches and so on but I like to call it Loh's method or Loh's alternative quadratic method as it was discussed by Professor Po-Shen Loh. He was the coach of the USA team that won International Mathematics Olympiad back to back. He is a professor of mathematics at Carnegie Mellon University. 1 Like |

Jodha: A newly discovered method last month. You just pick the coefficient of x, span it in the middle and equate to the C term. E. G If you are to solve X²-16x+48=0 16 is the coefficient of x. Half of 16 is 8. We just split this 8 into two parts and write (8+u)(8-u)=48 U²=16 U= +/- 4 Just subatitute +/-4 into (8+u) and (8-u) You will get 12 and 4 everytime. Therefore, X=4 or x =12 is the solution of the parent quadratic equation This method was discovered worldwide few weeks ago. |
