Simplifying
1080 = (x + 8)(2x + -8)

Reorder the terms:
1080 = (8 + x)(2x + -8)

Reorder the terms:
1080 = (8 + x)(-8 + 2x)

Multiply (8 + x) * (-8 + 2x)
1080 = (8(-8 + 2x) + x(-8 + 2x))
1080 = ((-8 * 8 + 2x * 8) + x(-8 + 2x))
1080 = ((-64 + 16x) + x(-8 + 2x))
1080 = (-64 + 16x + (-8 * x + 2x * x))
1080 = (-64 + 16x + (-8x + 2x2))

0 + x = 0 + -26
x = 0 + -26

Combine like terms: 0 + -26 = -26
x = -26

Simplifying
x = -26
Solution
x = {22, -26}
