Simplifying
2x(4x + 4) = x(2x + 1)

Reorder the terms:
2x(4 + 4x) = x(2x + 1)
(4 * 2x + 4x * 2x) = x(2x + 1)
(8x + 8x2) = x(2x + 1)

Reorder the terms:
8x + 8x2 = x(1 + 2x)
8x + 8x2 = (1 * x + 2x * x)
8x + 8x2 = (1x + 2x2)

Solving
8x + 8x2 = 1x + 2x2

Solving for variable 'x'.

Reorder the terms:
8x + -1x + 8x2 + -2x2 = 1x + 2x2 + -1x + -2x2

Combine like terms: 8x + -1x = 7x
7x + 8x2 + -2x2 = 1x + 2x2 + -1x + -2x2

Combine like terms: 8x2 + -2x2 = 6x2
7x + 6x2 = 1x + 2x2 + -1x + -2x2

Reorder the terms:
7x + 6x2 = 1x + -1x + 2x2 + -2x2

Combine like terms: 1x + -1x = 0
7x + 6x2 = 0 + 2x2 + -2x2
7x + 6x2 = 2x2 + -2x2

Combine like terms: 2x2 + -2x2 = 0
7x + 6x2 = 0

Factor out the Greatest Common Factor (GCF), 'x'.
x(7 + 6x) = 0

Subproblem 1

Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0

Subproblem 2

Set the factor '(7 + 6x)' equal to zero and attempt to solve: Simplifying 7 + 6x = 0 Solving 7 + 6x = 0 Move all terms containing x to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + 6x = 0 + -7 Combine like terms: 7 + -7 = 0 0 + 6x = 0 + -7 6x = 0 + -7 Combine like terms: 0 + -7 = -7 6x = -7 Divide each side by '6'. x = -1.166666667 Simplifying x = -1.166666667

Solution

x = {0, -1.166666667}
