Simplifying 4x + -2x(x + -2) = -9 + 5x + -8 Reorder the terms: 4x + -2x(-2 + x) = -9 + 5x + -8 4x + (-2 * -2x + x * -2x) = -9 + 5x + -8 4x + (4x + -2x2) = -9 + 5x + -8 Combine like terms: 4x + 4x = 8x 8x + -2x2 = -9 + 5x + -8 Reorder the terms: 8x + -2x2 = -9 + -8 + 5x Combine like terms: -9 + -8 = -17 8x + -2x2 = -17 + 5x Solving 8x + -2x2 = -17 + 5x Solving for variable 'x'. Reorder the terms: 17 + 8x + -5x + -2x2 = -17 + 5x + 17 + -5x Combine like terms: 8x + -5x = 3x 17 + 3x + -2x2 = -17 + 5x + 17 + -5x Reorder the terms: 17 + 3x + -2x2 = -17 + 17 + 5x + -5x Combine like terms: -17 + 17 = 0 17 + 3x + -2x2 = 0 + 5x + -5x 17 + 3x + -2x2 = 5x + -5x Combine like terms: 5x + -5x = 0 17 + 3x + -2x2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. -8.5 + -1.5x + x2 = 0 Move the constant term to the right: Add '8.5' to each side of the equation. -8.5 + -1.5x + 8.5 + x2 = 0 + 8.5 Reorder the terms: -8.5 + 8.5 + -1.5x + x2 = 0 + 8.5 Combine like terms: -8.5 + 8.5 = 0.0 0.0 + -1.5x + x2 = 0 + 8.5 -1.5x + x2 = 0 + 8.5 Combine like terms: 0 + 8.5 = 8.5 -1.5x + x2 = 8.5 The x term is -1.5x. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5x + 0.5625 + x2 = 8.5 + 0.5625 Reorder the terms: 0.5625 + -1.5x + x2 = 8.5 + 0.5625 Combine like terms: 8.5 + 0.5625 = 9.0625 0.5625 + -1.5x + x2 = 9.0625 Factor a perfect square on the left side: (x + -0.75)(x + -0.75) = 9.0625 Calculate the square root of the right side: 3.010398645 Break this problem into two subproblems by setting (x + -0.75) equal to 3.010398645 and -3.010398645.Subproblem 1
x + -0.75 = 3.010398645 Simplifying x + -0.75 = 3.010398645 Reorder the terms: -0.75 + x = 3.010398645 Solving -0.75 + x = 3.010398645 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + x = 3.010398645 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = 3.010398645 + 0.75 x = 3.010398645 + 0.75 Combine like terms: 3.010398645 + 0.75 = 3.760398645 x = 3.760398645 Simplifying x = 3.760398645Subproblem 2
x + -0.75 = -3.010398645 Simplifying x + -0.75 = -3.010398645 Reorder the terms: -0.75 + x = -3.010398645 Solving -0.75 + x = -3.010398645 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + x = -3.010398645 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = -3.010398645 + 0.75 x = -3.010398645 + 0.75 Combine like terms: -3.010398645 + 0.75 = -2.260398645 x = -2.260398645 Simplifying x = -2.260398645Solution
