Solution for (x-8)(x+9)=-2(x+31) equation:


Simplifying
(x + -8)(x + 9) = -2(x + 31)

Reorder the terms:
(-8 + x)(x + 9) = -2(x + 31)

Reorder the terms:
(-8 + x)(9 + x) = -2(x + 31)

Multiply (-8 + x) * (9 + x)
(-8(9 + x) + x(9 + x)) = -2(x + 31)
((9 * -8 + x * -8) + x(9 + x)) = -2(x + 31)
((-72 + -8x) + x(9 + x)) = -2(x + 31)
(-72 + -8x + (9 * x + x * x)) = -2(x + 31)
(-72 + -8x + (9x + x2)) = -2(x + 31)

Combine like terms: -8x + 9x = 1x
(-72 + 1x + x2) = -2(x + 31)
