Solution for (10-x)*(8-x)=8 equation:


Simplifying
(10 + -1x)(8 + -1x) = 8

Multiply (10 + -1x) * (8 + -1x)
(10(8 + -1x) + -1x * (8 + -1x)) = 8
((8 * 10 + -1x * 10) + -1x * (8 + -1x)) = 8
((80 + -10x) + -1x * (8 + -1x)) = 8
(80 + -10x + (8 * -1x + -1x * -1x)) = 8
(80 + -10x + (-8x + 1x2)) = 8

Combine like terms: -10x + -8x = -18x
(80 + -18x + 1x2) = 8

Solving
80 + -18x + 1x2 = 8
