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


Simplifying
(10 + -1x)(10 + -1x) = 0

Multiply (10 + -1x) * (10 + -1x)
(10(10 + -1x) + -1x * (10 + -1x)) = 0
((10 * 10 + -1x * 10) + -1x * (10 + -1x)) = 0
((100 + -10x) + -1x * (10 + -1x)) = 0
(100 + -10x + (10 * -1x + -1x * -1x)) = 0
(100 + -10x + (-10x + 1x2)) = 0

Combine like terms: -10x + -10x = -20x
(100 + -20x + 1x2) = 0
