Simplifying (x(14 + -2x)(25 + -2x)) = 0 Multiply (14 + -2x) * (25 + -2x) (x(14(25 + -2x) + -2x * (25 + -2x))) = 0 (x((25 * 14 + -2x * 14) + -2x * (25 + -2x))) = 0 (x((350 + -28x) + -2x * (25 + -2x))) = 0 (x(350 + -28x + (25 * -2x + -2x * -2x))) = 0 (x(350 + -28x + (-50x + 4x2))) = 0 Combine like terms: -28x + -50x = -78x (x(350 + -78x + 4x2)) = 0 ((350 * x + -78x * x + 4x2 * x)) = 0 ((350x + -78x2 + 4x3)) = 0 (350x + -78x2 + 4x3) = 0 Remove parenthesis around (350x + -78x2 + 4x3) 350x + -78x2 + 4x3 = 0 Solving 350x + -78x2 + 4x3 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2x'. 2x(175 + -39x + 2x2) = 0 Factor a trinomial. 2x((7 + -1x)(25 + -2x)) = 0 Ignore the factor 2.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 = 0Subproblem 2
Set the factor '(7 + -1x)' equal to zero and attempt to solve: Simplifying 7 + -1x = 0 Solving 7 + -1x = 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 + -1x = 0 + -7 Combine like terms: 7 + -7 = 0 0 + -1x = 0 + -7 -1x = 0 + -7 Combine like terms: 0 + -7 = -7 -1x = -7 Divide each side by '-1'. x = 7 Simplifying x = 7Subproblem 3
Set the factor '(25 + -2x)' equal to zero and attempt to solve: Simplifying 25 + -2x = 0 Solving 25 + -2x = 0 Move all terms containing x to the left, all other terms to the right. Add '-25' to each side of the equation. 25 + -25 + -2x = 0 + -25 Combine like terms: 25 + -25 = 0 0 + -2x = 0 + -25 -2x = 0 + -25 Combine like terms: 0 + -25 = -25 -2x = -25 Divide each side by '-2'. x = 12.5 Simplifying x = 12.5Solution
x = {0, 7, 12.5}
