Simplifying 2x2 + -39 = 10x Reorder the terms: -39 + 2x2 = 10x Solving -39 + 2x2 = 10x Solving for variable 'x'. Reorder the terms: -39 + -10x + 2x2 = 10x + -10x Combine like terms: 10x + -10x = 0 -39 + -10x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -19.5 + -5x + x2 = 0 Move the constant term to the right: Add '19.5' to each side of the equation. -19.5 + -5x + 19.5 + x2 = 0 + 19.5 Reorder the terms: -19.5 + 19.5 + -5x + x2 = 0 + 19.5 Combine like terms: -19.5 + 19.5 = 0.0 0.0 + -5x + x2 = 0 + 19.5 -5x + x2 = 0 + 19.5 Combine like terms: 0 + 19.5 = 19.5 -5x + x2 = 19.5 The x term is -5x. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5x + 6.25 + x2 = 19.5 + 6.25 Reorder the terms: 6.25 + -5x + x2 = 19.5 + 6.25 Combine like terms: 19.5 + 6.25 = 25.75 6.25 + -5x + x2 = 25.75 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = 25.75 Calculate the square root of the right side: 5.074445783 Break this problem into two subproblems by setting (x + -2.5) equal to 5.074445783 and -5.074445783.Subproblem 1
x + -2.5 = 5.074445783 Simplifying x + -2.5 = 5.074445783 Reorder the terms: -2.5 + x = 5.074445783 Solving -2.5 + x = 5.074445783 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = 5.074445783 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = 5.074445783 + 2.5 x = 5.074445783 + 2.5 Combine like terms: 5.074445783 + 2.5 = 7.574445783 x = 7.574445783 Simplifying x = 7.574445783Subproblem 2
x + -2.5 = -5.074445783 Simplifying x + -2.5 = -5.074445783 Reorder the terms: -2.5 + x = -5.074445783 Solving -2.5 + x = -5.074445783 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = -5.074445783 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = -5.074445783 + 2.5 x = -5.074445783 + 2.5 Combine like terms: -5.074445783 + 2.5 = -2.574445783 x = -2.574445783 Simplifying x = -2.574445783Solution
