Simplifying x = -1x2 + 16x + 8 Reorder the terms: x = 8 + 16x + -1x2 Solving x = 8 + 16x + -1x2 Solving for variable 'x'. Reorder the terms: -8 + x + -16x + x2 = 8 + 16x + -1x2 + -8 + -16x + x2 Combine like terms: x + -16x = -15x -8 + -15x + x2 = 8 + 16x + -1x2 + -8 + -16x + x2 Reorder the terms: -8 + -15x + x2 = 8 + -8 + 16x + -16x + -1x2 + x2 Combine like terms: 8 + -8 = 0 -8 + -15x + x2 = 0 + 16x + -16x + -1x2 + x2 -8 + -15x + x2 = 16x + -16x + -1x2 + x2 Combine like terms: 16x + -16x = 0 -8 + -15x + x2 = 0 + -1x2 + x2 -8 + -15x + x2 = -1x2 + x2 Combine like terms: -1x2 + x2 = 0 -8 + -15x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '8' to each side of the equation. -8 + -15x + 8 + x2 = 0 + 8 Reorder the terms: -8 + 8 + -15x + x2 = 0 + 8 Combine like terms: -8 + 8 = 0 0 + -15x + x2 = 0 + 8 -15x + x2 = 0 + 8 Combine like terms: 0 + 8 = 8 -15x + x2 = 8 The x term is -15x. Take half its coefficient (-7.5). Square it (56.25) and add it to both sides. Add '56.25' to each side of the equation. -15x + 56.25 + x2 = 8 + 56.25 Reorder the terms: 56.25 + -15x + x2 = 8 + 56.25 Combine like terms: 8 + 56.25 = 64.25 56.25 + -15x + x2 = 64.25 Factor a perfect square on the left side: (x + -7.5)(x + -7.5) = 64.25 Calculate the square root of the right side: 8.015609771 Break this problem into two subproblems by setting (x + -7.5) equal to 8.015609771 and -8.015609771.Subproblem 1
x + -7.5 = 8.015609771 Simplifying x + -7.5 = 8.015609771 Reorder the terms: -7.5 + x = 8.015609771 Solving -7.5 + x = 8.015609771 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '7.5' to each side of the equation. -7.5 + 7.5 + x = 8.015609771 + 7.5 Combine like terms: -7.5 + 7.5 = 0.0 0.0 + x = 8.015609771 + 7.5 x = 8.015609771 + 7.5 Combine like terms: 8.015609771 + 7.5 = 15.515609771 x = 15.515609771 Simplifying x = 15.515609771Subproblem 2
x + -7.5 = -8.015609771 Simplifying x + -7.5 = -8.015609771 Reorder the terms: -7.5 + x = -8.015609771 Solving -7.5 + x = -8.015609771 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '7.5' to each side of the equation. -7.5 + 7.5 + x = -8.015609771 + 7.5 Combine like terms: -7.5 + 7.5 = 0.0 0.0 + x = -8.015609771 + 7.5 x = -8.015609771 + 7.5 Combine like terms: -8.015609771 + 7.5 = -0.515609771 x = -0.515609771 Simplifying x = -0.515609771Solution
