Question

find the x-intercepts from these equations.

-4x^2 - 3x +1 = 0

2x^2 - 4x - 8 = 0

Answer 1

so like first step in case of the first equation divide both sides by -1 and will get

4x^2 +3x -1 = 0

in case of second equation factorize out the 2

2(x^2 -2x -4) = 0

divide both sides by 2

x^2 -2x -4 = 0
