Simplifying 5x2 + -40x + 20 = 0 Reorder the terms: 20 + -40x + 5x2 = 0 Solving 20 + -40x + 5x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '5'. 5(4 + -8x + x2) = 0 Ignore the factor 5.Subproblem 1
Set the factor '(4 + -8x + x2)' equal to zero and attempt to solve: Simplifying 4 + -8x + x2 = 0 Solving 4 + -8x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-4' to each side of the equation. 4 + -8x + -4 + x2 = 0 + -4 Reorder the terms: 4 + -4 + -8x + x2 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -8x + x2 = 0 + -4 -8x + x2 = 0 + -4 Combine like terms: 0 + -4 = -4 -8x + x2 = -4 The x term is -8x. Take half its coefficient (-4). Square it (16) and add it to both sides. Add '16' to each side of the equation. -8x + 16 + x2 = -4 + 16 Reorder the terms: 16 + -8x + x2 = -4 + 16 Combine like terms: -4 + 16 = 12 16 + -8x + x2 = 12 Factor a perfect square on the left side: (x + -4)(x + -4) = 12 Calculate the square root of the right side: 3.464101615 Break this problem into two subproblems by setting (x + -4) equal to 3.464101615 and -3.464101615.Subproblem 1
x + -4 = 3.464101615 Simplifying x + -4 = 3.464101615 Reorder the terms: -4 + x = 3.464101615 Solving -4 + x = 3.464101615 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + x = 3.464101615 + 4 Combine like terms: -4 + 4 = 0 0 + x = 3.464101615 + 4 x = 3.464101615 + 4 Combine like terms: 3.464101615 + 4 = 7.464101615 x = 7.464101615 Simplifying x = 7.464101615Subproblem 2
x + -4 = -3.464101615 Simplifying x + -4 = -3.464101615 Reorder the terms: -4 + x = -3.464101615 Solving -4 + x = -3.464101615 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + x = -3.464101615 + 4 Combine like terms: -4 + 4 = 0 0 + x = -3.464101615 + 4 x = -3.464101615 + 4 Combine like terms: -3.464101615 + 4 = 0.535898385 x = 0.535898385 Simplifying x = 0.535898385Solution
The solution to the problem is based on the solutions from the subproblems. x = {7.464101615, 0.535898385}Solution
x = {7.464101615, 0.535898385}
