Simplifying x = 2x2 + 6x + -4 Reorder the terms: x = -4 + 6x + 2x2 Solving x = -4 + 6x + 2x2 Solving for variable 'x'. Reorder the terms: 4 + x + -6x + -2x2 = -4 + 6x + 2x2 + 4 + -6x + -2x2 Combine like terms: x + -6x = -5x 4 + -5x + -2x2 = -4 + 6x + 2x2 + 4 + -6x + -2x2 Reorder the terms: 4 + -5x + -2x2 = -4 + 4 + 6x + -6x + 2x2 + -2x2 Combine like terms: -4 + 4 = 0 4 + -5x + -2x2 = 0 + 6x + -6x + 2x2 + -2x2 4 + -5x + -2x2 = 6x + -6x + 2x2 + -2x2 Combine like terms: 6x + -6x = 0 4 + -5x + -2x2 = 0 + 2x2 + -2x2 4 + -5x + -2x2 = 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 4 + -5x + -2x2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. -2 + 2.5x + x2 = 0 Move the constant term to the right: Add '2' to each side of the equation. -2 + 2.5x + 2 + x2 = 0 + 2 Reorder the terms: -2 + 2 + 2.5x + x2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 2.5x + x2 = 0 + 2 2.5x + x2 = 0 + 2 Combine like terms: 0 + 2 = 2 2.5x + x2 = 2 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 = 2 + 1.5625 Reorder the terms: 1.5625 + 2.5x + x2 = 2 + 1.5625 Combine like terms: 2 + 1.5625 = 3.5625 1.5625 + 2.5x + x2 = 3.5625 Factor a perfect square on the left side: (x + 1.25)(x + 1.25) = 3.5625 Calculate the square root of the right side: 1.887458609 Break this problem into two subproblems by setting (x + 1.25) equal to 1.887458609 and -1.887458609.Subproblem 1
x + 1.25 = 1.887458609 Simplifying x + 1.25 = 1.887458609 Reorder the terms: 1.25 + x = 1.887458609 Solving 1.25 + x = 1.887458609 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 = 1.887458609 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = 1.887458609 + -1.25 x = 1.887458609 + -1.25 Combine like terms: 1.887458609 + -1.25 = 0.637458609 x = 0.637458609 Simplifying x = 0.637458609Subproblem 2
x + 1.25 = -1.887458609 Simplifying x + 1.25 = -1.887458609 Reorder the terms: 1.25 + x = -1.887458609 Solving 1.25 + x = -1.887458609 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 = -1.887458609 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = -1.887458609 + -1.25 x = -1.887458609 + -1.25 Combine like terms: -1.887458609 + -1.25 = -3.137458609 x = -3.137458609 Simplifying x = -3.137458609Solution
