Simplifying (2x + 5) * x + -3 = 0 Reorder the terms: (5 + 2x) * x + -3 = 0 Reorder the terms for easier multiplication: x(5 + 2x) + -3 = 0 (5 * x + 2x * x) + -3 = 0 (5x + 2x2) + -3 = 0 Reorder the terms: -3 + 5x + 2x2 = 0 Solving -3 + 5x + 2x2 = 0 Solving for variable 'x'. Factor a trinomial. (-3 + -1x)(1 + -2x) = 0Subproblem 1
Set the factor '(-3 + -1x)' equal to zero and attempt to solve: Simplifying -3 + -1x = 0 Solving -3 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '3' to each side of the equation. -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 = -3Subproblem 2
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 = 0.5Solution
x = {-3, 0.5}
