Simplifying x2 + -15x + 16 = 0 Reorder the terms: 16 + -15x + x2 = 0 Solving 16 + -15x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-16' to each side of the equation. 16 + -15x + -16 + x2 = 0 + -16 Reorder the terms: 16 + -16 + -15x + x2 = 0 + -16 Combine like terms: 16 + -16 = 0 0 + -15x + x2 = 0 + -16 -15x + x2 = 0 + -16 Combine like terms: 0 + -16 = -16 -15x + x2 = -16 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 = -16 + 56.25 Reorder the terms: 56.25 + -15x + x2 = -16 + 56.25 Combine like terms: -16 + 56.25 = 40.25 56.25 + -15x + x2 = 40.25 Factor a perfect square on the left side: (x + -7.5)(x + -7.5) = 40.25 Calculate the square root of the right side: 6.34428877 Break this problem into two subproblems by setting (x + -7.5) equal to 6.34428877 and -6.34428877.Subproblem 1
x + -7.5 = 6.34428877 Simplifying x + -7.5 = 6.34428877 Reorder the terms: -7.5 + x = 6.34428877 Solving -7.5 + x = 6.34428877 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 = 6.34428877 + 7.5 Combine like terms: -7.5 + 7.5 = 0.0 0.0 + x = 6.34428877 + 7.5 x = 6.34428877 + 7.5 Combine like terms: 6.34428877 + 7.5 = 13.84428877 x = 13.84428877 Simplifying x = 13.84428877Subproblem 2
x + -7.5 = -6.34428877 Simplifying x + -7.5 = -6.34428877 Reorder the terms: -7.5 + x = -6.34428877 Solving -7.5 + x = -6.34428877 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 = -6.34428877 + 7.5 Combine like terms: -7.5 + 7.5 = 0.0 0.0 + x = -6.34428877 + 7.5 x = -6.34428877 + 7.5 Combine like terms: -6.34428877 + 7.5 = 1.15571123 x = 1.15571123 Simplifying x = 1.15571123Solution
