Simplifying 0 = x2 + 15x + -160 Reorder the terms: 0 = -160 + 15x + x2 Solving 0 = -160 + 15x + x2 Solving for variable 'x'. Combine like terms: 0 + 160 = 160 160 + -15x + -1x2 = -160 + 15x + x2 + 160 + -15x + -1x2 Reorder the terms: 160 + -15x + -1x2 = -160 + 160 + 15x + -15x + x2 + -1x2 Combine like terms: -160 + 160 = 0 160 + -15x + -1x2 = 0 + 15x + -15x + x2 + -1x2 160 + -15x + -1x2 = 15x + -15x + x2 + -1x2 Combine like terms: 15x + -15x = 0 160 + -15x + -1x2 = 0 + x2 + -1x2 160 + -15x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 160 + -15x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -160 + 15x + x2 = 0 Move the constant term to the right: Add '160' to each side of the equation. -160 + 15x + 160 + x2 = 0 + 160 Reorder the terms: -160 + 160 + 15x + x2 = 0 + 160 Combine like terms: -160 + 160 = 0 0 + 15x + x2 = 0 + 160 15x + x2 = 0 + 160 Combine like terms: 0 + 160 = 160 15x + x2 = 160 The x term is 15x. Take half its coefficient (7.5). Square it (56.25) and add it to both sides. Add '56.25' to each side of the equation. 15x + 56.25 + x2 = 160 + 56.25 Reorder the terms: 56.25 + 15x + x2 = 160 + 56.25 Combine like terms: 160 + 56.25 = 216.25 56.25 + 15x + x2 = 216.25 Factor a perfect square on the left side: (x + 7.5)(x + 7.5) = 216.25 Calculate the square root of the right side: 14.70544117 Break this problem into two subproblems by setting (x + 7.5) equal to 14.70544117 and -14.70544117.Subproblem 1
x + 7.5 = 14.70544117 Simplifying x + 7.5 = 14.70544117 Reorder the terms: 7.5 + x = 14.70544117 Solving 7.5 + x = 14.70544117 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7.5' to each side of the equation. 7.5 + -7.5 + x = 14.70544117 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + x = 14.70544117 + -7.5 x = 14.70544117 + -7.5 Combine like terms: 14.70544117 + -7.5 = 7.20544117 x = 7.20544117 Simplifying x = 7.20544117Subproblem 2
x + 7.5 = -14.70544117 Simplifying x + 7.5 = -14.70544117 Reorder the terms: 7.5 + x = -14.70544117 Solving 7.5 + x = -14.70544117 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7.5' to each side of the equation. 7.5 + -7.5 + x = -14.70544117 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + x = -14.70544117 + -7.5 x = -14.70544117 + -7.5 Combine like terms: -14.70544117 + -7.5 = -22.20544117 x = -22.20544117 Simplifying x = -22.20544117Solution
The solution to the problem is based on the solutions from the subproblems. x = {7.20544117, -22.20544117}
