This year's jamb exam kicks off from the 27th NOT 29th. You guys should go and reprint o. I have. My exam date is sooner than expected - 27th of this month. That's 7 days from now. I no know why jamb carry me put with the first batch. |

Please mathlethes quick question If some strips of stick of length 7cm 9cm and 27cm were cut independently from a tree find d shortest possible length of d stem A 197cm B 54cm C 81cm D 189cm I have seen d solution to d Q but still can't comprehend d method applied so I brought here wit hopes of gettn a good explanation... Thanks in adv....d tutors here a doing a great job God bless u all |
Re: Nairaland 2016 Jamb Tutorial Classroon [mathematics Thread] by stoicguy(m): 6:46am On Feb 22, 2016 |
lekelistik:Shortest possible length = least common multiple. LCM ... . . simply find the LCM of the the numbers which is your ans . . 189 . My view though ... you can as well wait for the ogas them. |
Re: Nairaland 2016 Jamb Tutorial Classroon [mathematics Thread] by Oxytocin(m): 9:13am On Feb 22, 2016 |
lekelistik:Just like stoicguy said.. Find the LCM of the numbers 3. 7 |9 |27 3. 7 |3 |9 3. 7 | 1| 3 7. 7 | 1| 1 . . .1|1 | 1 So it will be.. 3× 3× 3×7=189 |

If the sum of the first two terms of a G.P is 3, and the sum of the second and the third term is -6, find the sum of the first and the common ratio. Thankyoujesus, mathefaro, shyneptune, oxytocin, orezy5 etc. |
Re: Nairaland 2016 Jamb Tutorial Classroon [mathematics Thread] by Oxytocin(m): 12:22pm On Feb 24, 2016 |
Geofavor:From Tn=ar^n-1 1st term=a 2nd term=ar 3rd term =ar² a+ ar=3 ar+ar²=-6 a(1+r)=3..............(i) ar(1+r)=-6............(ii) Divide (ii) by (i) r=-2 Substitute - 2 for r in...... (i) a(1+(-2) =3 a(-1)=3 a =-3 Sum of first(a) and common ratio(r) =a +r=-3 + -2 =-5 |

Factorize x3+2x2-5x-6=0 |
Re: Nairaland 2016 Jamb Tutorial Classroon [mathematics Thread] by Umartins1(m): 3:26pm On Mar 01, 2016 |
parkparky: Try x= -1 (-1)3 + 2(-1)2 - 5(-1) -6 = 0 -1+2+5-6=0 0=0 Therefore x=-1 x+1=0 Divide the polynomial by x+1 You will get x2+x-6 Solve x2+x-6=0 x2+3x-2x-6= 0 x(x+3)-2(x+3)= 0 (x-2)(x+3) = 0 x=2 or x= -3 Therefore, x=-1, 2 or -3 |
Re: Nairaland 2016 Jamb Tutorial Classroon [mathematics Thread] by Geofavor(m): 7:18pm On Mar 01, 2016 |
Umartins1:can I ask, what was the basis of your guessing that x = -1? Or was it just a trial and error with random numbers? |
Re: Nairaland 2016 Jamb Tutorial Classroon [mathematics Thread] by parkparky(m): 7:26pm On Mar 01, 2016 |
Umartins1:must we use x=-1 in all cases |
Re: Nairaland 2016 Jamb Tutorial Classroon [mathematics Thread] by mathefaro(m): 8:35pm On Mar 01, 2016 |
I guess I need to chip in my quota here, parkparky: Geofavor:The "-1" is not just a random number, we are expected to try out all the factors of the constant polynomial which is "-6" in this case. Apparently, the numbers we can use here (factors of -6) include ±1, ±2, ±3 and ±6. And according to factors theorem, if after trying x = -2 and it gives you zero i.e. f(-2) =0, it means x +2 is a factor of the polynomial. Then we can get the other factors by using the long division and subsequently factoring whatever quotient we get. Mind you, this is the traditional (omoluabi) method. Jambites ain't advised to try this in the hall. Just cross check your options(expand the brackets) one after the other to see the one that works. It saves you done time and stress. **winks** |
Re: Nairaland 2016 Jamb Tutorial Classroon [mathematics Thread] by Geofavor(m): 8:53pm On Mar 01, 2016 |
mathefaro:you're right. I saw a question like this one during the exam. Me wey no get time for nonsense, . . . I skip am sharpally. |
