Simplifying x(2x + 5) + (2x + 5 + -12) = 108 Reorder the terms: x(5 + 2x) + (2x + 5 + -12) = 108 (5 * x + 2x * x) + (2x + 5 + -12) = 108 (5x + 2x2) + (2x + 5 + -12) = 108 Reorder the terms: 5x + 2x2 + (5 + -12 + 2x) = 108 Combine like terms: 5 + -12 = -7 5x + 2x2 + (-7 + 2x) = 108 Remove parenthesis around (-7 + 2x) 5x + 2x2 + -7 + 2x = 108 Reorder the terms: -7 + 5x + 2x + 2x2 = 108 Combine like terms: 5x + 2x = 7x -7 + 7x + 2x2 = 108 Solving -7 + 7x + 2x2 = 108 Solving for variable 'x'. Reorder the terms: -7 + -108 + 7x + 2x2 = 108 + -108 Combine like terms: -7 + -108 = -115 -115 + 7x + 2x2 = 108 + -108 Combine like terms: 108 + -108 = 0 -115 + 7x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -57.5 + 3.5x + x2 = 0 Move the constant term to the right: Add '57.5' to each side of the equation. -57.5 + 3.5x + 57.5 + x2 = 0 + 57.5 Reorder the terms: -57.5 + 57.5 + 3.5x + x2 = 0 + 57.5 Combine like terms: -57.5 + 57.5 = 0.0 0.0 + 3.5x + x2 = 0 + 57.5 3.5x + x2 = 0 + 57.5 Combine like terms: 0 + 57.5 = 57.5 3.5x + x2 = 57.5 The x term is 3.5x. Take half its coefficient (1.75). Square it (3.0625) and add it to both sides. Add '3.0625' to each side of the equation. 3.5x + 3.0625 + x2 = 57.5 + 3.0625 Reorder the terms: 3.0625 + 3.5x + x2 = 57.5 + 3.0625 Combine like terms: 57.5 + 3.0625 = 60.5625 3.0625 + 3.5x + x2 = 60.5625 Factor a perfect square on the left side: (x + 1.75)(x + 1.75) = 60.5625 Calculate the square root of the right side: 7.782191208 Break this problem into two subproblems by setting (x + 1.75) equal to 7.782191208 and -7.782191208.Subproblem 1
x + 1.75 = 7.782191208 Simplifying x + 1.75 = 7.782191208 Reorder the terms: 1.75 + x = 7.782191208 Solving 1.75 + x = 7.782191208 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.75' to each side of the equation. 1.75 + -1.75 + x = 7.782191208 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + x = 7.782191208 + -1.75 x = 7.782191208 + -1.75 Combine like terms: 7.782191208 + -1.75 = 6.032191208 x = 6.032191208 Simplifying x = 6.032191208Subproblem 2
x + 1.75 = -7.782191208 Simplifying x + 1.75 = -7.782191208 Reorder the terms: 1.75 + x = -7.782191208 Solving 1.75 + x = -7.782191208 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.75' to each side of the equation. 1.75 + -1.75 + x = -7.782191208 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + x = -7.782191208 + -1.75 x = -7.782191208 + -1.75 Combine like terms: -7.782191208 + -1.75 = -9.532191208 x = -9.532191208 Simplifying x = -9.532191208Solution
