Simplifying 2x2 + 2x + -39 = 0 Reorder the terms: -39 + 2x + 2x2 = 0 Solving -39 + 2x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -19.5 + x + x2 = 0 Move the constant term to the right: Add '19.5' to each side of the equation. -19.5 + x + 19.5 + x2 = 0 + 19.5 Reorder the terms: -19.5 + 19.5 + x + x2 = 0 + 19.5 Combine like terms: -19.5 + 19.5 = 0.0 0.0 + x + x2 = 0 + 19.5 x + x2 = 0 + 19.5 Combine like terms: 0 + 19.5 = 19.5 x + x2 = 19.5 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. + 0.25 + x2 = 19.5 + 0.25 Combine like terms: + 0.25 = 1.25 1.25 + x2 = 19.5 + 0.25 Combine like terms: 19.5 + 0.25 = 19.75 1.25 + x2 = 19.75 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 19.75 Calculate the square root of the right side: 4.444097209 Break this problem into two subproblems by setting (x + 0.5) equal to 4.444097209 and -4.444097209.Subproblem 1
x + 0.5 = 4.444097209 Simplifying x + 0.5 = 4.444097209 Reorder the terms: 0.5 + x = 4.444097209 Solving 0.5 + x = 4.444097209 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 = 4.444097209 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 4.444097209 + -0.5 x = 4.444097209 + -0.5 Combine like terms: 4.444097209 + -0.5 = 3.944097209 x = 3.944097209 Simplifying x = 3.944097209Subproblem 2
x + 0.5 = -4.444097209 Simplifying x + 0.5 = -4.444097209 Reorder the terms: 0.5 + x = -4.444097209 Solving 0.5 + x = -4.444097209 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 = -4.444097209 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -4.444097209 + -0.5 x = -4.444097209 + -0.5 Combine like terms: -4.444097209 + -0.5 = -4.944097209 x = -4.944097209 Simplifying x = -4.944097209Solution
