Simplifying 4x(x + 2) = 4x + -1 Reorder the terms: 4x(2 + x) = 4x + -1 (2 * 4x + x * 4x) = 4x + -1 (8x + 4x2) = 4x + -1 Reorder the terms: 8x + 4x2 = -1 + 4x Solving 8x + 4x2 = -1 + 4x Solving for variable 'x'. Reorder the terms: 1 + 8x + -4x + 4x2 = -1 + 4x + 1 + -4x Combine like terms: 8x + -4x = 4x 1 + 4x + 4x2 = -1 + 4x + 1 + -4x Reorder the terms: 1 + 4x + 4x2 = -1 + 1 + 4x + -4x Combine like terms: -1 + 1 = 0 1 + 4x + 4x2 = 0 + 4x + -4x 1 + 4x + 4x2 = 4x + -4x Combine like terms: 4x + -4x = 0 1 + 4x + 4x2 = 0 Factor a trinomial. (1 + 2x)(1 + 2x) = 0Subproblem 1
Set the factor '(1 + 2x)' equal to zero and attempt to solve: Simplifying 1 + 2x = 0 Solving 1 + 2x = 0 Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + 2x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 2x = 0 + -1 2x = 0 + -1 Combine like terms: 0 + -1 = -1 2x = -1 Divide each side by '2'. x = -0.5 Simplifying x = -0.5Subproblem 2
