Simplifying -7x2 + -21x = 14 Reorder the terms: -21x + -7x2 = 14 Solving -21x + -7x2 = 14 Solving for variable 'x'. Reorder the terms: -14 + -21x + -7x2 = 14 + -14 Combine like terms: 14 + -14 = 0 -14 + -21x + -7x2 = 0 Factor out the Greatest Common Factor (GCF), '-7'. -7(2 + 3x + x2) = 0 Factor a trinomial. -7((2 + x)(1 + x)) = 0 Ignore the factor -7.Subproblem 1
Set the factor '(2 + x)' equal to zero and attempt to solve: Simplifying 2 + x = 0 Solving 2 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + x = 0 + -2 x = 0 + -2 Combine like terms: 0 + -2 = -2 x = -2 Simplifying x = -2Subproblem 2
Set the factor '(1 + x)' equal to zero and attempt to solve: Simplifying 1 + x = 0 Solving 1 + x = 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 + x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + x = 0 + -1 x = 0 + -1 Combine like terms: 0 + -1 = -1 x = -1 Simplifying x = -1Solution
x = {-2, -1}
