Simplifying 2x2 = x + 20 Reorder the terms: 2x2 = 20 + x Solving 2x2 = 20 + x Solving for variable 'x'. Reorder the terms: -20 + -1x + 2x2 = 20 + x + -20 + -1x Reorder the terms: -20 + -1x + 2x2 = 20 + -20 + x + -1x Combine like terms: 20 + -20 = 0 -20 + -1x + 2x2 = 0 + x + -1x -20 + -1x + 2x2 = x + -1x Combine like terms: x + -1x = 0 -20 + -1x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -10 + -0.5x + x2 = 0 Move the constant term to the right: Add '10' to each side of the equation. -10 + -0.5x + 10 + x2 = 0 + 10 Reorder the terms: -10 + 10 + -0.5x + x2 = 0 + 10 Combine like terms: -10 + 10 = 0 0 + -0.5x + x2 = 0 + 10 -0.5x + x2 = 0 + 10 Combine like terms: 0 + 10 = 10 -0.5x + x2 = 10 The x term is -0.5x. Take half its coefficient (-0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. -0.5x + 0.0625 + x2 = 10 + 0.0625 Reorder the terms: 0.0625 + -0.5x + x2 = 10 + 0.0625 Combine like terms: 10 + 0.0625 = 10.0625 0.0625 + -0.5x + x2 = 10.0625 Factor a perfect square on the left side: (x + -0.25)(x + -0.25) = 10.0625 Calculate the square root of the right side: 3.172144385 Break this problem into two subproblems by setting (x + -0.25) equal to 3.172144385 and -3.172144385.Subproblem 1
x + -0.25 = 3.172144385 Simplifying x + -0.25 = 3.172144385 Reorder the terms: -0.25 + x = 3.172144385 Solving -0.25 + x = 3.172144385 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + x = 3.172144385 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + x = 3.172144385 + 0.25 x = 3.172144385 + 0.25 Combine like terms: 3.172144385 + 0.25 = 3.422144385 x = 3.422144385 Simplifying x = 3.422144385Subproblem 2
x + -0.25 = -3.172144385 Simplifying x + -0.25 = -3.172144385 Reorder the terms: -0.25 + x = -3.172144385 Solving -0.25 + x = -3.172144385 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + x = -3.172144385 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + x = -3.172144385 + 0.25 x = -3.172144385 + 0.25 Combine like terms: -3.172144385 + 0.25 = -2.922144385 x = -2.922144385 Simplifying x = -2.922144385Solution
