Solution for (y+8)(y-12)=0 equation:


Simplifying
(y + 8)(y + -12) = 0

Reorder the terms:
(8 + y)(y + -12) = 0

Reorder the terms:
(8 + y)(-12 + y) = 0

Multiply (8 + y) * (-12 + y)
(8(-12 + y) + y(-12 + y)) = 0
((-12 * 8 + y * 8) + y(-12 + y)) = 0
((-96 + 8y) + y(-12 + y)) = 0
(-96 + 8y + (-12 * y + y * y)) = 0
(-96 + 8y + (-12y + y2)) = 0

Combine like terms: 8y + -12y = -4y
(-96 + -4y + y2) = 0

Solving
-96 + -4y + y2 = 0
