I am getting desperate. Can someone please help me with this and thank you in ADVANCE!!!!
WRITE A QUADRATIC EQUATION IN THE variable x given the solutions: -sqrt7,
7sqrt7.This needs to be in the standard form ax^2 + bx+c=0. I really need help as this is due in about 2 hours.
(x+sqrt7)(x - 7sqrt7) = 0
has those solutions.
Multiply it out.
x^2 -6sqrt7*x -49 = 0
