Simplifying 2x(x + 7) + 9 = 180 Reorder the terms: 2x(7 + x) + 9 = 180 (7 * 2x + x * 2x) + 9 = 180 (14x + 2x2) + 9 = 180 Reorder the terms: 9 + 14x + 2x2 = 180 Solving 9 + 14x + 2x2 = 180 Solving for variable 'x'. Reorder the terms: 9 + -180 + 14x + 2x2 = 180 + -180 Combine like terms: 9 + -180 = -171 -171 + 14x + 2x2 = 180 + -180 Combine like terms: 180 + -180 = 0 -171 + 14x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -85.5 + 7x + x2 = 0 Move the constant term to the right: Add '85.5' to each side of the equation. -85.5 + 7x + 85.5 + x2 = 0 + 85.5 Reorder the terms: -85.5 + 85.5 + 7x + x2 = 0 + 85.5 Combine like terms: -85.5 + 85.5 = 0.0 0.0 + 7x + x2 = 0 + 85.5 7x + x2 = 0 + 85.5 Combine like terms: 0 + 85.5 = 85.5 7x + x2 = 85.5 The x term is 7x. Take half its coefficient (3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. 7x + 12.25 + x2 = 85.5 + 12.25 Reorder the terms: 12.25 + 7x + x2 = 85.5 + 12.25 Combine like terms: 85.5 + 12.25 = 97.75 12.25 + 7x + x2 = 97.75 Factor a perfect square on the left side: (x + 3.5)(x + 3.5) = 97.75 Calculate the square root of the right side: 9.886859967 Break this problem into two subproblems by setting (x + 3.5) equal to 9.886859967 and -9.886859967.Subproblem 1
x + 3.5 = 9.886859967 Simplifying x + 3.5 = 9.886859967 Reorder the terms: 3.5 + x = 9.886859967 Solving 3.5 + x = 9.886859967 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + x = 9.886859967 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = 9.886859967 + -3.5 x = 9.886859967 + -3.5 Combine like terms: 9.886859967 + -3.5 = 6.386859967 x = 6.386859967 Simplifying x = 6.386859967Subproblem 2
x + 3.5 = -9.886859967 Simplifying x + 3.5 = -9.886859967 Reorder the terms: 3.5 + x = -9.886859967 Solving 3.5 + x = -9.886859967 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + x = -9.886859967 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = -9.886859967 + -3.5 x = -9.886859967 + -3.5 Combine like terms: -9.886859967 + -3.5 = -13.386859967 x = -13.386859967 Simplifying x = -13.386859967Solution
The solution to the problem is based on the solutions from the subproblems. x = {6.386859967, -13.386859967}
