Simplifying 4x(2x + 9) = -15 Reorder the terms: 4x(9 + 2x) = -15 (9 * 4x + 2x * 4x) = -15 (36x + 8x2) = -15 Solving 36x + 8x2 = -15 Solving for variable 'x'. Reorder the terms: 15 + 36x + 8x2 = -15 + 15 Combine like terms: -15 + 15 = 0 15 + 36x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 1.875 + 4.5x + x2 = 0 Move the constant term to the right: Add '-1.875' to each side of the equation. 1.875 + 4.5x + -1.875 + x2 = 0 + -1.875 Reorder the terms: 1.875 + -1.875 + 4.5x + x2 = 0 + -1.875 Combine like terms: 1.875 + -1.875 = 0.000 0.000 + 4.5x + x2 = 0 + -1.875 4.5x + x2 = 0 + -1.875 Combine like terms: 0 + -1.875 = -1.875 4.5x + x2 = -1.875 The x term is 4.5x. Take half its coefficient (2.25). Square it (5.0625) and add it to both sides. Add '5.0625' to each side of the equation. 4.5x + 5.0625 + x2 = -1.875 + 5.0625 Reorder the terms: 5.0625 + 4.5x + x2 = -1.875 + 5.0625 Combine like terms: -1.875 + 5.0625 = 3.1875 5.0625 + 4.5x + x2 = 3.1875 Factor a perfect square on the left side: (x + 2.25)(x + 2.25) = 3.1875 Calculate the square root of the right side: 1.785357107 Break this problem into two subproblems by setting (x + 2.25) equal to 1.785357107 and -1.785357107.Subproblem 1
x + 2.25 = 1.785357107 Simplifying x + 2.25 = 1.785357107 Reorder the terms: 2.25 + x = 1.785357107 Solving 2.25 + x = 1.785357107 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.25' to each side of the equation. 2.25 + -2.25 + x = 1.785357107 + -2.25 Combine like terms: 2.25 + -2.25 = 0.00 0.00 + x = 1.785357107 + -2.25 x = 1.785357107 + -2.25 Combine like terms: 1.785357107 + -2.25 = -0.464642893 x = -0.464642893 Simplifying x = -0.464642893Subproblem 2
x + 2.25 = -1.785357107 Simplifying x + 2.25 = -1.785357107 Reorder the terms: 2.25 + x = -1.785357107 Solving 2.25 + x = -1.785357107 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.25' to each side of the equation. 2.25 + -2.25 + x = -1.785357107 + -2.25 Combine like terms: 2.25 + -2.25 = 0.00 0.00 + x = -1.785357107 + -2.25 x = -1.785357107 + -2.25 Combine like terms: -1.785357107 + -2.25 = -4.035357107 x = -4.035357107 Simplifying x = -4.035357107Solution
