Find the solution to 36z^2+96z+15=0

Answer 1

divide the original answer by 3
and get

12Z^2 + 32Z + 5 = 0

now find common factor of 12, that work for the equation

(6Z + 1)(2Z +5)=0

6Z = -1
z= -1/6

2Z = -5
Z= -5/2

now plug each Z value in to the equation (one at a time) and see which Z value lets the equation equal to zero.

Answer 2

this answer is wrong, the answer would be -5/2, -1/6
