Simplifying 4x(x + 2) = 165 Reorder the terms: 4x(2 + x) = 165 (2 * 4x + x * 4x) = 165 (8x + 4x2) = 165 Solving 8x + 4x2 = 165 Solving for variable 'x'. Reorder the terms: -165 + 8x + 4x2 = 165 + -165 Combine like terms: 165 + -165 = 0 -165 + 8x + 4x2 = 0 Factor a trinomial. (-15 + -2x)(11 + -2x) = 0Subproblem 1
Set the factor '(-15 + -2x)' equal to zero and attempt to solve: Simplifying -15 + -2x = 0 Solving -15 + -2x = 0 Move all terms containing x to the left, all other terms to the right. Add '15' to each side of the equation. -15 + 15 + -2x = 0 + 15 Combine like terms: -15 + 15 = 0 0 + -2x = 0 + 15 -2x = 0 + 15 Combine like terms: 0 + 15 = 15 -2x = 15 Divide each side by '-2'. x = -7.5 Simplifying x = -7.5Subproblem 2
Set the factor '(11 + -2x)' equal to zero and attempt to solve: Simplifying 11 + -2x = 0 Solving 11 + -2x = 0 Move all terms containing x to the left, all other terms to the right. Add '-11' to each side of the equation. 11 + -11 + -2x = 0 + -11 Combine like terms: 11 + -11 = 0 0 + -2x = 0 + -11 -2x = 0 + -11 Combine like terms: 0 + -11 = -11 -2x = -11 Divide each side by '-2'. x = 5.5 Simplifying x = 5.5Solution
x = {-7.5, 5.5}
