Simplifying 2x2 + -5x + -39 = 0 Reorder the terms: -39 + -5x + 2x2 = 0 Solving -39 + -5x + 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 + -2.5x + x2 = 0 Move the constant term to the right: Add '19.5' to each side of the equation. -19.5 + -2.5x + 19.5 + x2 = 0 + 19.5 Reorder the terms: -19.5 + 19.5 + -2.5x + x2 = 0 + 19.5 Combine like terms: -19.5 + 19.5 = 0.0 0.0 + -2.5x + x2 = 0 + 19.5 -2.5x + x2 = 0 + 19.5 Combine like terms: 0 + 19.5 = 19.5 -2.5x + x2 = 19.5 The x term is -2.5x. Take half its coefficient (-1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. -2.5x + 1.5625 + x2 = 19.5 + 1.5625 Reorder the terms: 1.5625 + -2.5x + x2 = 19.5 + 1.5625 Combine like terms: 19.5 + 1.5625 = 21.0625 1.5625 + -2.5x + x2 = 21.0625 Factor a perfect square on the left side: (x + -1.25)(x + -1.25) = 21.0625 Calculate the square root of the right side: 4.589389938 Break this problem into two subproblems by setting (x + -1.25) equal to 4.589389938 and -4.589389938.Subproblem 1
x + -1.25 = 4.589389938 Simplifying x + -1.25 = 4.589389938 Reorder the terms: -1.25 + x = 4.589389938 Solving -1.25 + x = 4.589389938 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + x = 4.589389938 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + x = 4.589389938 + 1.25 x = 4.589389938 + 1.25 Combine like terms: 4.589389938 + 1.25 = 5.839389938 x = 5.839389938 Simplifying x = 5.839389938Subproblem 2
x + -1.25 = -4.589389938 Simplifying x + -1.25 = -4.589389938 Reorder the terms: -1.25 + x = -4.589389938 Solving -1.25 + x = -4.589389938 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + x = -4.589389938 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + x = -4.589389938 + 1.25 x = -4.589389938 + 1.25 Combine like terms: -4.589389938 + 1.25 = -3.339389938 x = -3.339389938 Simplifying x = -3.339389938Solution
