Simplifying -2x(x + -3) + 5x = -15 Reorder the terms: -2x(-3 + x) + 5x = -15 (-3 * -2x + x * -2x) + 5x = -15 (6x + -2x2) + 5x = -15 Reorder the terms: 6x + 5x + -2x2 = -15 Combine like terms: 6x + 5x = 11x 11x + -2x2 = -15 Solving 11x + -2x2 = -15 Solving for variable 'x'. Reorder the terms: 15 + 11x + -2x2 = -15 + 15 Combine like terms: -15 + 15 = 0 15 + 11x + -2x2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. -7.5 + -5.5x + x2 = 0 Move the constant term to the right: Add '7.5' to each side of the equation. -7.5 + -5.5x + 7.5 + x2 = 0 + 7.5 Reorder the terms: -7.5 + 7.5 + -5.5x + x2 = 0 + 7.5 Combine like terms: -7.5 + 7.5 = 0.0 0.0 + -5.5x + x2 = 0 + 7.5 -5.5x + x2 = 0 + 7.5 Combine like terms: 0 + 7.5 = 7.5 -5.5x + x2 = 7.5 The x term is -5.5x. Take half its coefficient (-2.75). Square it (7.5625) and add it to both sides. Add '7.5625' to each side of the equation. -5.5x + 7.5625 + x2 = 7.5 + 7.5625 Reorder the terms: 7.5625 + -5.5x + x2 = 7.5 + 7.5625 Combine like terms: 7.5 + 7.5625 = 15.0625 7.5625 + -5.5x + x2 = 15.0625 Factor a perfect square on the left side: (x + -2.75)(x + -2.75) = 15.0625 Calculate the square root of the right side: 3.881043674 Break this problem into two subproblems by setting (x + -2.75) equal to 3.881043674 and -3.881043674.Subproblem 1
x + -2.75 = 3.881043674 Simplifying x + -2.75 = 3.881043674 Reorder the terms: -2.75 + x = 3.881043674 Solving -2.75 + x = 3.881043674 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.75' to each side of the equation. -2.75 + 2.75 + x = 3.881043674 + 2.75 Combine like terms: -2.75 + 2.75 = 0.00 0.00 + x = 3.881043674 + 2.75 x = 3.881043674 + 2.75 Combine like terms: 3.881043674 + 2.75 = 6.631043674 x = 6.631043674 Simplifying x = 6.631043674Subproblem 2
x + -2.75 = -3.881043674 Simplifying x + -2.75 = -3.881043674 Reorder the terms: -2.75 + x = -3.881043674 Solving -2.75 + x = -3.881043674 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.75' to each side of the equation. -2.75 + 2.75 + x = -3.881043674 + 2.75 Combine like terms: -2.75 + 2.75 = 0.00 0.00 + x = -3.881043674 + 2.75 x = -3.881043674 + 2.75 Combine like terms: -3.881043674 + 2.75 = -1.131043674 x = -1.131043674 Simplifying x = -1.131043674Solution
