(x-1)(x-1)(10)=40

Solution for (x-1)(x-1)(10)=40 equation:

Simplifying
(x + -1)(x + -1)(10) = 40

Reorder the terms:
(-1 + x)(x + -1)(10) = 40

Reorder the terms:
(-1 + x)(-1 + x)(10) = 40

Reorder the terms for easier multiplication:
10(-1 + x)(-1 + x) = 40

Multiply (-1 + x) * (-1 + x)
10(-1(-1 + x) + x(-1 + x)) = 40
10((-1 * -1 + x * -1) + x(-1 + x)) = 40
10((1 + -1x) + x(-1 + x)) = 40
10(1 + -1x + (-1 * x + x * x)) = 40
10(1 + -1x + (-1x + x2)) = 40

Combine like terms: -1x + -1x = -2x
10(1 + -2x + x2) = 40
(1 * 10 + -2x * 10 + x2 * 10) = 40
(10 + -20x + 10x2) = 40

Solving
10 + -20x + 10x2 = 40

Solving for variable 'x'.

Reorder the terms:
10 + -40 + -20x + 10x2 = 40 + -40

Combine like terms: 10 + -40 = -30
-30 + -20x + 10x2 = 40 + -40

Combine like terms: 40 + -40 = 0
-30 + -20x + 10x2 = 0

Factor out the Greatest Common Factor (GCF), '10'.

3 + -3 + -1x = 0 + -3

Combine like terms: 3 + -3 = 0
0 + -1x = 0 + -3
-1x = 0 + -3

Combine like terms: 0 + -3 = -3
-1x = -3

Divide each side by '-1'.
x = 3

Simplifying
x = 3
Solution
x = {-1, 3}
