Simplifying 4x2 + 3x = -7x Reorder the terms: 3x + 4x2 = -7x Solving 3x + 4x2 = -7x Solving for variable 'x'. Reorder the terms: 3x + 7x + 4x2 = -7x + 7x Combine like terms: 3x + 7x = 10x 10x + 4x2 = -7x + 7x Combine like terms: -7x + 7x = 0 10x + 4x2 = 0 Factor out the Greatest Common Factor (GCF), '2x'. 2x(5 + 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 '(5 + 2x)' equal to zero and attempt to solve: Simplifying 5 + 2x = 0 Solving 5 + 2x = 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 + 2x = 0 + -5 Combine like terms: 5 + -5 = 0 0 + 2x = 0 + -5 2x = 0 + -5 Combine like terms: 0 + -5 = -5 2x = -5 Divide each side by '2'. x = -2.5 Simplifying x = -2.5Solution
x = {0, -2.5}
