Simplifying 2x2 + -40x + 50 = 0 Reorder the terms: 50 + -40x + 2x2 = 0 Solving 50 + -40x + 2x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(25 + -20x + x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(25 + -20x + x2)' equal to zero and attempt to solve: Simplifying 25 + -20x + x2 = 0 Solving 25 + -20x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-25' to each side of the equation. 25 + -20x + -25 + x2 = 0 + -25 Reorder the terms: 25 + -25 + -20x + x2 = 0 + -25 Combine like terms: 25 + -25 = 0 0 + -20x + x2 = 0 + -25 -20x + x2 = 0 + -25 Combine like terms: 0 + -25 = -25 -20x + x2 = -25 The x term is -20x. Take half its coefficient (-10). Square it (100) and add it to both sides. Add '100' to each side of the equation. -20x + 100 + x2 = -25 + 100 Reorder the terms: 100 + -20x + x2 = -25 + 100 Combine like terms: -25 + 100 = 75 100 + -20x + x2 = 75 Factor a perfect square on the left side: (x + -10)(x + -10) = 75 Calculate the square root of the right side: 8.660254038 Break this problem into two subproblems by setting (x + -10) equal to 8.660254038 and -8.660254038.Subproblem 1
x + -10 = 8.660254038 Simplifying x + -10 = 8.660254038 Reorder the terms: -10 + x = 8.660254038 Solving -10 + x = 8.660254038 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '10' to each side of the equation. -10 + 10 + x = 8.660254038 + 10 Combine like terms: -10 + 10 = 0 0 + x = 8.660254038 + 10 x = 8.660254038 + 10 Combine like terms: 8.660254038 + 10 = 18.660254038 x = 18.660254038 Simplifying x = 18.660254038Subproblem 2
x + -10 = -8.660254038 Simplifying x + -10 = -8.660254038 Reorder the terms: -10 + x = -8.660254038 Solving -10 + x = -8.660254038 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '10' to each side of the equation. -10 + 10 + x = -8.660254038 + 10 Combine like terms: -10 + 10 = 0 0 + x = -8.660254038 + 10 x = -8.660254038 + 10 Combine like terms: -8.660254038 + 10 = 1.339745962 x = 1.339745962 Simplifying x = 1.339745962Solution
