Simplifying 2x2 + -15x + 16 = 0 Reorder the terms: 16 + -15x + 2x2 = 0 Solving 16 + -15x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 8 + -7.5x + x2 = 0 Move the constant term to the right: Add '-8' to each side of the equation. 8 + -7.5x + -8 + x2 = 0 + -8 Reorder the terms: 8 + -8 + -7.5x + x2 = 0 + -8 Combine like terms: 8 + -8 = 0 0 + -7.5x + x2 = 0 + -8 -7.5x + x2 = 0 + -8 Combine like terms: 0 + -8 = -8 -7.5x + x2 = -8 The x term is -7.5x. Take half its coefficient (-3.75). Square it (14.0625) and add it to both sides. Add '14.0625' to each side of the equation. -7.5x + 14.0625 + x2 = -8 + 14.0625 Reorder the terms: 14.0625 + -7.5x + x2 = -8 + 14.0625 Combine like terms: -8 + 14.0625 = 6.0625 14.0625 + -7.5x + x2 = 6.0625 Factor a perfect square on the left side: (x + -3.75)(x + -3.75) = 6.0625 Calculate the square root of the right side: 2.46221445 Break this problem into two subproblems by setting (x + -3.75) equal to 2.46221445 and -2.46221445.Subproblem 1
x + -3.75 = 2.46221445 Simplifying x + -3.75 = 2.46221445 Reorder the terms: -3.75 + x = 2.46221445 Solving -3.75 + x = 2.46221445 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.75' to each side of the equation. -3.75 + 3.75 + x = 2.46221445 + 3.75 Combine like terms: -3.75 + 3.75 = 0.00 0.00 + x = 2.46221445 + 3.75 x = 2.46221445 + 3.75 Combine like terms: 2.46221445 + 3.75 = 6.21221445 x = 6.21221445 Simplifying x = 6.21221445Subproblem 2
x + -3.75 = -2.46221445 Simplifying x + -3.75 = -2.46221445 Reorder the terms: -3.75 + x = -2.46221445 Solving -3.75 + x = -2.46221445 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.75' to each side of the equation. -3.75 + 3.75 + x = -2.46221445 + 3.75 Combine like terms: -3.75 + 3.75 = 0.00 0.00 + x = -2.46221445 + 3.75 x = -2.46221445 + 3.75 Combine like terms: -2.46221445 + 3.75 = 1.28778555 x = 1.28778555 Simplifying x = 1.28778555Solution
