Simplifying -16x2 + 20x + 15 = 0 Reorder the terms: 15 + 20x + -16x2 = 0 Solving 15 + 20x + -16x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -16 the coefficient of the squared term: Divide each side by '-16'. -0.9375 + -1.25x + x2 = 0 Move the constant term to the right: Add '0.9375' to each side of the equation. -0.9375 + -1.25x + 0.9375 + x2 = 0 + 0.9375 Reorder the terms: -0.9375 + 0.9375 + -1.25x + x2 = 0 + 0.9375 Combine like terms: -0.9375 + 0.9375 = 0.0000 0.0000 + -1.25x + x2 = 0 + 0.9375 -1.25x + x2 = 0 + 0.9375 Combine like terms: 0 + 0.9375 = 0.9375 -1.25x + x2 = 0.9375 The x term is -1.25x. Take half its coefficient (-0.625). Square it (0.390625) and add it to both sides. Add '0.390625' to each side of the equation. -1.25x + 0.390625 + x2 = 0.9375 + 0.390625 Reorder the terms: 0.390625 + -1.25x + x2 = 0.9375 + 0.390625 Combine like terms: 0.9375 + 0.390625 = 1.328125 0.390625 + -1.25x + x2 = 1.328125 Factor a perfect square on the left side: (x + -0.625)(x + -0.625) = 1.328125 Calculate the square root of the right side: 1.152443057 Break this problem into two subproblems by setting (x + -0.625) equal to 1.152443057 and -1.152443057.Subproblem 1
x + -0.625 = 1.152443057 Simplifying x + -0.625 = 1.152443057 Reorder the terms: -0.625 + x = 1.152443057 Solving -0.625 + x = 1.152443057 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.625' to each side of the equation. -0.625 + 0.625 + x = 1.152443057 + 0.625 Combine like terms: -0.625 + 0.625 = 0.000 0.000 + x = 1.152443057 + 0.625 x = 1.152443057 + 0.625 Combine like terms: 1.152443057 + 0.625 = 1.777443057 x = 1.777443057 Simplifying x = 1.777443057Subproblem 2
x + -0.625 = -1.152443057 Simplifying x + -0.625 = -1.152443057 Reorder the terms: -0.625 + x = -1.152443057 Solving -0.625 + x = -1.152443057 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.625' to each side of the equation. -0.625 + 0.625 + x = -1.152443057 + 0.625 Combine like terms: -0.625 + 0.625 = 0.000 0.000 + x = -1.152443057 + 0.625 x = -1.152443057 + 0.625 Combine like terms: -1.152443057 + 0.625 = -0.527443057 x = -0.527443057 Simplifying x = -0.527443057Solution
