Simplifying 16x2 + 56x + 49 = 81 Reorder the terms: 49 + 56x + 16x2 = 81 Solving 49 + 56x + 16x2 = 81 Solving for variable 'x'. Reorder the terms: 49 + -81 + 56x + 16x2 = 81 + -81 Combine like terms: 49 + -81 = -32 -32 + 56x + 16x2 = 81 + -81 Combine like terms: 81 + -81 = 0 -32 + 56x + 16x2 = 0 Factor out the Greatest Common Factor (GCF), '8'. 8(-4 + 7x + 2x2) = 0 Factor a trinomial. 8((-4 + -1x)(1 + -2x)) = 0 Ignore the factor 8.Subproblem 1
Set the factor '(-4 + -1x)' equal to zero and attempt to solve: Simplifying -4 + -1x = 0 Solving -4 + -1x = 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 + -1x = 0 + 4 Combine like terms: -4 + 4 = 0 0 + -1x = 0 + 4 -1x = 0 + 4 Combine like terms: 0 + 4 = 4 -1x = 4 Divide each side by '-1'. x = -4 Simplifying x = -4Subproblem 2
Set the factor '(1 + -2x)' equal to zero and attempt to solve: Simplifying 1 + -2x = 0 Solving 1 + -2x = 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 + -2x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -2x = 0 + -1 -2x = 0 + -1 Combine like terms: 0 + -1 = -1 -2x = -1 Divide each side by '-2'. x = 0.5 Simplifying x = 0.5Solution
x = {-4, 0.5}
