Simplifying -8x(x + -2) + -29 = -13 Reorder the terms: -8x(-2 + x) + -29 = -13 (-2 * -8x + x * -8x) + -29 = -13 (16x + -8x2) + -29 = -13 Reorder the terms: -29 + 16x + -8x2 = -13 Solving -29 + 16x + -8x2 = -13 Solving for variable 'x'. Reorder the terms: -29 + 13 + 16x + -8x2 = -13 + 13 Combine like terms: -29 + 13 = -16 -16 + 16x + -8x2 = -13 + 13 Combine like terms: -13 + 13 = 0 -16 + 16x + -8x2 = 0 Factor out the Greatest Common Factor (GCF), '8'. 8(-2 + 2x + -1x2) = 0 Ignore the factor 8.Subproblem 1
Set the factor '(-2 + 2x + -1x2)' equal to zero and attempt to solve: Simplifying -2 + 2x + -1x2 = 0 Solving -2 + 2x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 2 + -2x + x2 = 0 Move the constant term to the right: Add '-2' to each side of the equation. 2 + -2x + -2 + x2 = 0 + -2 Reorder the terms: 2 + -2 + -2x + x2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -2x + x2 = 0 + -2 -2x + x2 = 0 + -2 Combine like terms: 0 + -2 = -2 -2x + x2 = -2 The x term is -2x. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2x + 1 + x2 = -2 + 1 Reorder the terms: 1 + -2x + x2 = -2 + 1 Combine like terms: -2 + 1 = -1 1 + -2x + x2 = -1 Factor a perfect square on the left side: (x + -1)(x + -1) = -1 Can't calculate square root of the right side.
