Simplifying (8x + 7) + -1(2x2 + -5x + -5) = 0 Reorder the terms: (7 + 8x) + -1(2x2 + -5x + -5) = 0 Remove parenthesis around (7 + 8x) 7 + 8x + -1(2x2 + -5x + -5) = 0 Reorder the terms: 7 + 8x + -1(-5 + -5x + 2x2) = 0 7 + 8x + (-5 * -1 + -5x * -1 + 2x2 * -1) = 0 7 + 8x + (5 + 5x + -2x2) = 0 Reorder the terms: 7 + 5 + 8x + 5x + -2x2 = 0 Combine like terms: 7 + 5 = 12 12 + 8x + 5x + -2x2 = 0 Combine like terms: 8x + 5x = 13x 12 + 13x + -2x2 = 0 Solving 12 + 13x + -2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. -6 + -6.5x + x2 = 0 Move the constant term to the right: Add '6' to each side of the equation. -6 + -6.5x + 6 + x2 = 0 + 6 Reorder the terms: -6 + 6 + -6.5x + x2 = 0 + 6 Combine like terms: -6 + 6 = 0 0 + -6.5x + x2 = 0 + 6 -6.5x + x2 = 0 + 6 Combine like terms: 0 + 6 = 6 -6.5x + x2 = 6 The x term is -6.5x. Take half its coefficient (-3.25). Square it (10.5625) and add it to both sides. Add '10.5625' to each side of the equation. -6.5x + 10.5625 + x2 = 6 + 10.5625 Reorder the terms: 10.5625 + -6.5x + x2 = 6 + 10.5625 Combine like terms: 6 + 10.5625 = 16.5625 10.5625 + -6.5x + x2 = 16.5625 Factor a perfect square on the left side: (x + -3.25)(x + -3.25) = 16.5625 Calculate the square root of the right side: 4.069705149 Break this problem into two subproblems by setting (x + -3.25) equal to 4.069705149 and -4.069705149.Subproblem 1
x + -3.25 = 4.069705149 Simplifying x + -3.25 = 4.069705149 Reorder the terms: -3.25 + x = 4.069705149 Solving -3.25 + x = 4.069705149 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.25' to each side of the equation. -3.25 + 3.25 + x = 4.069705149 + 3.25 Combine like terms: -3.25 + 3.25 = 0.00 0.00 + x = 4.069705149 + 3.25 x = 4.069705149 + 3.25 Combine like terms: 4.069705149 + 3.25 = 7.319705149 x = 7.319705149 Simplifying x = 7.319705149Subproblem 2
x + -3.25 = -4.069705149 Simplifying x + -3.25 = -4.069705149 Reorder the terms: -3.25 + x = -4.069705149 Solving -3.25 + x = -4.069705149 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.25' to each side of the equation. -3.25 + 3.25 + x = -4.069705149 + 3.25 Combine like terms: -3.25 + 3.25 = 0.00 0.00 + x = -4.069705149 + 3.25 x = -4.069705149 + 3.25 Combine like terms: -4.069705149 + 3.25 = -0.819705149 x = -0.819705149 Simplifying x = -0.819705149Solution
