Simplifying -1x2 + -40x + -80 = 0 Reorder the terms: -80 + -40x + -1x2 = 0 Solving -80 + -40x + -1x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '-1'. -1(80 + 40x + x2) = 0 Ignore the factor -1.Subproblem 1
Set the factor '(80 + 40x + x2)' equal to zero and attempt to solve: Simplifying 80 + 40x + x2 = 0 Solving 80 + 40x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-80' to each side of the equation. 80 + 40x + -80 + x2 = 0 + -80 Reorder the terms: 80 + -80 + 40x + x2 = 0 + -80 Combine like terms: 80 + -80 = 0 0 + 40x + x2 = 0 + -80 40x + x2 = 0 + -80 Combine like terms: 0 + -80 = -80 40x + x2 = -80 The x term is 40x. Take half its coefficient (20). Square it (400) and add it to both sides. Add '400' to each side of the equation. 40x + 400 + x2 = -80 + 400 Reorder the terms: 400 + 40x + x2 = -80 + 400 Combine like terms: -80 + 400 = 320 400 + 40x + x2 = 320 Factor a perfect square on the left side: (x + 20)(x + 20) = 320 Calculate the square root of the right side: 17.88854382 Break this problem into two subproblems by setting (x + 20) equal to 17.88854382 and -17.88854382.Subproblem 1
x + 20 = 17.88854382 Simplifying x + 20 = 17.88854382 Reorder the terms: 20 + x = 17.88854382 Solving 20 + x = 17.88854382 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-20' to each side of the equation. 20 + -20 + x = 17.88854382 + -20 Combine like terms: 20 + -20 = 0 0 + x = 17.88854382 + -20 x = 17.88854382 + -20 Combine like terms: 17.88854382 + -20 = -2.11145618 x = -2.11145618 Simplifying x = -2.11145618Subproblem 2
x + 20 = -17.88854382 Simplifying x + 20 = -17.88854382 Reorder the terms: 20 + x = -17.88854382 Solving 20 + x = -17.88854382 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-20' to each side of the equation. 20 + -20 + x = -17.88854382 + -20 Combine like terms: 20 + -20 = 0 0 + x = -17.88854382 + -20 x = -17.88854382 + -20 Combine like terms: -17.88854382 + -20 = -37.88854382 x = -37.88854382 Simplifying x = -37.88854382Solution
The solution to the problem is based on the solutions from the subproblems. x = {-2.11145618, -37.88854382}Solution
x = {-2.11145618, -37.88854382}
