Simplifying 4x2 + 12x + 9 + -1(9x2 + 42x + 49) = 0 Reorder the terms: 4x2 + 12x + 9 + -1(49 + 42x + 9x2) = 0 4x2 + 12x + 9 + (49 * -1 + 42x * -1 + 9x2 * -1) = 0 4x2 + 12x + 9 + (-49 + -42x + -9x2) = 0 Reorder the terms: 9 + -49 + 12x + -42x + 4x2 + -9x2 = 0 Combine like terms: 9 + -49 = -40 -40 + 12x + -42x + 4x2 + -9x2 = 0 Combine like terms: 12x + -42x = -30x -40 + -30x + 4x2 + -9x2 = 0 Combine like terms: 4x2 + -9x2 = -5x2 -40 + -30x + -5x2 = 0 Solving -40 + -30x + -5x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '-5'. -5(8 + 6x + x2) = 0 Factor a trinomial. -5((4 + x)(2 + x)) = 0 Ignore the factor -5.Subproblem 1
Set the factor '(4 + x)' equal to zero and attempt to solve: Simplifying 4 + x = 0 Solving 4 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + x = 0 + -4 Combine like terms: 4 + -4 = 0 0 + x = 0 + -4 x = 0 + -4 Combine like terms: 0 + -4 = -4 x = -4 Simplifying x = -4Subproblem 2
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 = -2Solution
x = {-4, -2}
