Simplifying 9x2 + x2 + 7x + x2 = 0 Reorder the terms: 7x + 9x2 + x2 + x2 = 0 Combine like terms: 9x2 + x2 = 10x2 7x + 10x2 + x2 = 0 Combine like terms: 10x2 + x2 = 11x2 7x + 11x2 = 0 Solving 7x + 11x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), 'x'. x(7 + 11x) = 0Subproblem 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 + 11x)' equal to zero and attempt to solve: Simplifying 7 + 11x = 0 Solving 7 + 11x = 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 + 11x = 0 + -7 Combine like terms: 7 + -7 = 0 0 + 11x = 0 + -7 11x = 0 + -7 Combine like terms: 0 + -7 = -7 11x = -7 Divide each side by '11'. x = -0.6363636364 Simplifying x = -0.6363636364Solution
x = {0, -0.6363636364}
