Simplifying -21x2 = 15x Solving -21x2 = 15x Solving for variable 'x'. Reorder the terms: -15x + -21x2 = 15x + -15x Combine like terms: 15x + -15x = 0 -15x + -21x2 = 0 Factor out the Greatest Common Factor (GCF), '-3x'. -3x(5 + 7x) = 0 Ignore the factor -3.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 '(5 + 7x)' equal to zero and attempt to solve: Simplifying 5 + 7x = 0 Solving 5 + 7x = 0 Move all terms containing x to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + 7x = 0 + -5 Combine like terms: 5 + -5 = 0 0 + 7x = 0 + -5 7x = 0 + -5 Combine like terms: 0 + -5 = -5 7x = -5 Divide each side by '7'. x = -0.7142857143 Simplifying x = -0.7142857143Solution
x = {0, -0.7142857143}
