Simplifying
(x + 6)(x + -8) = 26

Reorder the terms:
(6 + x)(x + -8) = 26

Reorder the terms:
(6 + x)(-8 + x) = 26

Multiply (6 + x) * (-8 + x)
(6(-8 + x) + x(-8 + x)) = 26
((-8 * 6 + x * 6) + x(-8 + x)) = 26
((-48 + 6x) + x(-8 + x)) = 26
(-48 + 6x + (-8 * x + x * x)) = 26
(-48 + 6x + (-8x + x2)) = 26

Combine like terms: 6x + -8x = -2x
(-48 + -2x + x2) = 26

Solving
-48 + -2x + x2 = 26

Solving for variable 'x'.

Reorder the terms:
-48 + -26 + -2x + x2 = 26 + -26
