Simplifying (3x2 + -4x + 8) + -1(x2 + 7x + -5) = 0 Reorder the terms: (8 + -4x + 3x2) + -1(x2 + 7x + -5) = 0 Remove parenthesis around (8 + -4x + 3x2) 8 + -4x + 3x2 + -1(x2 + 7x + -5) = 0 Reorder the terms: 8 + -4x + 3x2 + -1(-5 + 7x + x2) = 0 8 + -4x + 3x2 + (-5 * -1 + 7x * -1 + x2 * -1) = 0 8 + -4x + 3x2 + (5 + -7x + -1x2) = 0 Reorder the terms: 8 + 5 + -4x + -7x + 3x2 + -1x2 = 0 Combine like terms: 8 + 5 = 13 13 + -4x + -7x + 3x2 + -1x2 = 0 Combine like terms: -4x + -7x = -11x 13 + -11x + 3x2 + -1x2 = 0 Combine like terms: 3x2 + -1x2 = 2x2 13 + -11x + 2x2 = 0 Solving 13 + -11x + 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'. 6.5 + -5.5x + x2 = 0 Move the constant term to the right: Add '-6.5' to each side of the equation. 6.5 + -5.5x + -6.5 + x2 = 0 + -6.5 Reorder the terms: 6.5 + -6.5 + -5.5x + x2 = 0 + -6.5 Combine like terms: 6.5 + -6.5 = 0.0 0.0 + -5.5x + x2 = 0 + -6.5 -5.5x + x2 = 0 + -6.5 Combine like terms: 0 + -6.5 = -6.5 -5.5x + x2 = -6.5 The x term is -5.5x. Take half its coefficient (-2.75). Square it (7.5625) and add it to both sides. Add '7.5625' to each side of the equation. -5.5x + 7.5625 + x2 = -6.5 + 7.5625 Reorder the terms: 7.5625 + -5.5x + x2 = -6.5 + 7.5625 Combine like terms: -6.5 + 7.5625 = 1.0625 7.5625 + -5.5x + x2 = 1.0625 Factor a perfect square on the left side: (x + -2.75)(x + -2.75) = 1.0625 Calculate the square root of the right side: 1.030776406 Break this problem into two subproblems by setting (x + -2.75) equal to 1.030776406 and -1.030776406.Subproblem 1
x + -2.75 = 1.030776406 Simplifying x + -2.75 = 1.030776406 Reorder the terms: -2.75 + x = 1.030776406 Solving -2.75 + x = 1.030776406 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.75' to each side of the equation. -2.75 + 2.75 + x = 1.030776406 + 2.75 Combine like terms: -2.75 + 2.75 = 0.00 0.00 + x = 1.030776406 + 2.75 x = 1.030776406 + 2.75 Combine like terms: 1.030776406 + 2.75 = 3.780776406 x = 3.780776406 Simplifying x = 3.780776406Subproblem 2
