Simplifying 20 = 2x2 + -2x + 2 Reorder the terms: 20 = 2 + -2x + 2x2 Solving 20 = 2 + -2x + 2x2 Solving for variable 'x'. Combine like terms: 20 + -2 = 18 18 + 2x + -2x2 = 2 + -2x + 2x2 + -2 + 2x + -2x2 Reorder the terms: 18 + 2x + -2x2 = 2 + -2 + -2x + 2x + 2x2 + -2x2 Combine like terms: 2 + -2 = 0 18 + 2x + -2x2 = 0 + -2x + 2x + 2x2 + -2x2 18 + 2x + -2x2 = -2x + 2x + 2x2 + -2x2 Combine like terms: -2x + 2x = 0 18 + 2x + -2x2 = 0 + 2x2 + -2x2 18 + 2x + -2x2 = 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 18 + 2x + -2x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(9 + x + -1x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(9 + x + -1x2)' equal to zero and attempt to solve: Simplifying 9 + x + -1x2 = 0 Solving 9 + x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -9 + -1x + x2 = 0 Move the constant term to the right: Add '9' to each side of the equation. -9 + -1x + 9 + x2 = 0 + 9 Reorder the terms: -9 + 9 + -1x + x2 = 0 + 9 Combine like terms: -9 + 9 = 0 0 + -1x + x2 = 0 + 9 -1x + x2 = 0 + 9 Combine like terms: 0 + 9 = 9 -1x + x2 = 9 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1x + 0.25 + x2 = 9 + 0.25 Reorder the terms: 0.25 + -1x + x2 = 9 + 0.25 Combine like terms: 9 + 0.25 = 9.25 0.25 + -1x + x2 = 9.25 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 9.25 Calculate the square root of the right side: 3.041381265 Break this problem into two subproblems by setting (x + 0.5) equal to 3.041381265 and -3.041381265.Subproblem 1
x + 0.5 = 3.041381265 Simplifying x + 0.5 = 3.041381265 Reorder the terms: 0.5 + x = 3.041381265 Solving 0.5 + x = 3.041381265 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = 3.041381265 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 3.041381265 + -0.5 x = 3.041381265 + -0.5 Combine like terms: 3.041381265 + -0.5 = 2.541381265 x = 2.541381265 Simplifying x = 2.541381265Subproblem 2
x + 0.5 = -3.041381265 Simplifying x + 0.5 = -3.041381265 Reorder the terms: 0.5 + x = -3.041381265 Solving 0.5 + x = -3.041381265 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = -3.041381265 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -3.041381265 + -0.5 x = -3.041381265 + -0.5 Combine like terms: -3.041381265 + -0.5 = -3.541381265 x = -3.541381265 Simplifying x = -3.541381265Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.541381265, -3.541381265}Solution
x = {2.541381265, -3.541381265}
