Simplifying 0 = 4x2 + -8x + -80 Reorder the terms: 0 = -80 + -8x + 4x2 Solving 0 = -80 + -8x + 4x2 Solving for variable 'x'. Combine like terms: 0 + 80 = 80 80 + 8x + -4x2 = -80 + -8x + 4x2 + 80 + 8x + -4x2 Reorder the terms: 80 + 8x + -4x2 = -80 + 80 + -8x + 8x + 4x2 + -4x2 Combine like terms: -80 + 80 = 0 80 + 8x + -4x2 = 0 + -8x + 8x + 4x2 + -4x2 80 + 8x + -4x2 = -8x + 8x + 4x2 + -4x2 Combine like terms: -8x + 8x = 0 80 + 8x + -4x2 = 0 + 4x2 + -4x2 80 + 8x + -4x2 = 4x2 + -4x2 Combine like terms: 4x2 + -4x2 = 0 80 + 8x + -4x2 = 0 Factor out the Greatest Common Factor (GCF), '4'. 4(20 + 2x + -1x2) = 0 Ignore the factor 4.Subproblem 1
Set the factor '(20 + 2x + -1x2)' equal to zero and attempt to solve: Simplifying 20 + 2x + -1x2 = 0 Solving 20 + 2x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -20 + -2x + x2 = 0 Move the constant term to the right: Add '20' to each side of the equation. -20 + -2x + 20 + x2 = 0 + 20 Reorder the terms: -20 + 20 + -2x + x2 = 0 + 20 Combine like terms: -20 + 20 = 0 0 + -2x + x2 = 0 + 20 -2x + x2 = 0 + 20 Combine like terms: 0 + 20 = 20 -2x + x2 = 20 The x term is -2x. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2x + 1 + x2 = 20 + 1 Reorder the terms: 1 + -2x + x2 = 20 + 1 Combine like terms: 20 + 1 = 21 1 + -2x + x2 = 21 Factor a perfect square on the left side: (x + -1)(x + -1) = 21 Calculate the square root of the right side: 4.582575695 Break this problem into two subproblems by setting (x + -1) equal to 4.582575695 and -4.582575695.Subproblem 1
x + -1 = 4.582575695 Simplifying x + -1 = 4.582575695 Reorder the terms: -1 + x = 4.582575695 Solving -1 + x = 4.582575695 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = 4.582575695 + 1 Combine like terms: -1 + 1 = 0 0 + x = 4.582575695 + 1 x = 4.582575695 + 1 Combine like terms: 4.582575695 + 1 = 5.582575695 x = 5.582575695 Simplifying x = 5.582575695Subproblem 2
x + -1 = -4.582575695 Simplifying x + -1 = -4.582575695 Reorder the terms: -1 + x = -4.582575695 Solving -1 + x = -4.582575695 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = -4.582575695 + 1 Combine like terms: -1 + 1 = 0 0 + x = -4.582575695 + 1 x = -4.582575695 + 1 Combine like terms: -4.582575695 + 1 = -3.582575695 x = -3.582575695 Simplifying x = -3.582575695Solution
The solution to the problem is based on the solutions from the subproblems. x = {5.582575695, -3.582575695}Solution
x = {5.582575695, -3.582575695}
