Seun, lalasticlala, mynd44, nlfpmod Please you guys should add support MathJax to this forum so that we can benefit from seeing better formated mathematical equations. I think that will boost the activity of helping people with calculations in the education section. Thank you. |

sqlPAIN: Idi0t!! "Quadratic formula" and "completing the square method" are one and the same method. Quadratic formula can be derived from completing the square. |

[quote author=sqlPAIN post=120223160]The first one has to be solved with the quadratic formula, I know how to solve it with other methods but when I use quadratic, I keep getting wrong answers..... The second one has to be solved with completing the square method.. [/ quote] Are you a beginner? If not, no big worries in the questions. |

I know the questions are no big deal but I decided to allow ChatGPT solve them. See the output below: Quadratic Formula Solution Solve Solve X^2 + 2X - 8 = 0 Using the quadratic formula The quadratic formula for solving the equation ax^2 + bx + c = 0 is: x = (-b ± √(b^2 - 4ac)) / 2a So in this case, we have: x^2 + 2x - 8 = 0 x = (-2 ± √(2^2 - 4(1)(-)) / 2(1) x = (-2 ± √(4 + 32)) / 2 x = (-2 ± √(36)) / 2 x = (-2 ± 6) / 2 x = (-2 + 6) / 2 or x = (-2 - 6) / 2 x = 2 or x = -4 Therefore, the solutions of the equation are x = 2 and x = -4 Solve X^2 - 3X - 18 = 0 using completing the Square To solve x^2 - 3x - 18 = 0 using completing the square method, we can follow these steps: Rewrite the equation in the form of x^2 - 3x = 18 by adding 18 to both sides. Add (3/2)^2 to both sides of the equation to get a perfect square trinomial on one side of the equation: (x-3/2)^2 = (3/2)^2 + 18. Take the square root of both sides of the equation: x-3/2 = ± √((3/2)^2 + 18) Add 3/2 to both sides of the equation: x = 3/2 ± √((3/2)^2 + 18) Solve for x by simplifying the square root: x = 3/2 ± √(9/4 + 18) = 3/2 ± √(81/4) = 3/2 ± 3/2 = 6 or x = -3 Therefore, the solutions of the equation are x = 6 and x = -3. 1 Like |

The solutions to the quadratic equation X^2 + 2x - 8 = 0 are x = -4 and x = 2. You can use Quadratic Formula : x = (-b ± √(b^2-4ac)) / 2a In this case a=1, b=2 and c=-8. x = (-2 ± √(2^2-41(-)) / 2*1 x = (-2 ± √(4+32)) / 2 x = (-2 ± √(36)) / 2 x = (-2 ± 6) / 2 x = (-4) / 2 or x = 2/2 x = -2 or x = 1 Source: ChatGPT |
