Solution for (10)(10)=(x+2)(x+2)+x^2 equation:


Simplifying
(10)(10) = (x + 2)(x + 2) + x2

Multiply 10 * 10
100 = (x + 2)(x + 2) + x2

Reorder the terms:
100 = (2 + x)(x + 2) + x2

Reorder the terms:
100 = (2 + x)(2 + x) + x2

Multiply (2 + x) * (2 + x)
100 = (2(2 + x) + x(2 + x)) + x2
100 = ((2 * 2 + x * 2) + x(2 + x)) + x2
100 = ((4 + 2x) + x(2 + x)) + x2
100 = (4 + 2x + (2 * x + x * x)) + x2
100 = (4 + 2x + (2x + x2)) + x2

Combine like terms: 2x + 2x = 4x
100 = (4 + 4x + x2) + x2

Combine like terms: x2 + x2 = 2x2
100 = 4 + 4x + 2x2

Solving
100 = 4 + 4x + 2x2

Solving for variable 'x'.

Combine like terms: 100 + -4 = 96
96 + -4x + -2x2 = 4 + 4x + 2x2 + -4 + -4x + -2x2

Reorder the terms:
96 + -4x + -2x2 = 4 + -4 + 4x + -4x + 2x2 + -2x2

Combine like terms: 4 + -4 = 0
96 + -4x + -2x2 = 0 + 4x + -4x + 2x2 + -2x2
96 + -4x + -2x2 = 4x + -4x + 2x2 + -2x2

Combine like terms: 4x + -4x = 0
96 + -4x + -2x2 = 0 + 2x2 + -2x2
96 + -4x + -2x2 = 2x2 + -2x2

Combine like terms: 2x2 + -2x2 = 0
96 + -4x + -2x2 = 0

Factor out the Greatest Common Factor (GCF), '2'.
2(48 + -2x + -1x2) = 0

Subproblem 1

Set the factor '(6 + -1x)' equal to zero and attempt to solve: Simplifying 6 + -1x = 0 Solving 6 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + -1x = 0 + -6 Combine like terms: 6 + -6 = 0 0 + -1x = 0 + -6 -1x = 0 + -6 Combine like terms: 0 + -6 = -6 -1x = -6 Divide each side by '-1'. x = 6 Simplifying x = 6

Subproblem 2

Set the factor '(8 + x)' equal to zero and attempt to solve: Simplifying 8 + x = 0 Solving 8 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + x = 0 + -8 Combine like terms: 8 + -8 = 0 0 + x = 0 + -8 x = 0 + -8 Combine like terms: 0 + -8 = -8 x = -8 Simplifying x = -8

Solution

x = {6, -8}
