Simplifying 0 = -16x2 + 64x + -20 Reorder the terms: 0 = -20 + 64x + -16x2 Solving 0 = -20 + 64x + -16x2 Solving for variable 'x'. Combine like terms: 0 + 20 = 20 20 + -64x + 16x2 = -20 + 64x + -16x2 + 20 + -64x + 16x2 Reorder the terms: 20 + -64x + 16x2 = -20 + 20 + 64x + -64x + -16x2 + 16x2 Combine like terms: -20 + 20 = 0 20 + -64x + 16x2 = 0 + 64x + -64x + -16x2 + 16x2 20 + -64x + 16x2 = 64x + -64x + -16x2 + 16x2 Combine like terms: 64x + -64x = 0 20 + -64x + 16x2 = 0 + -16x2 + 16x2 20 + -64x + 16x2 = -16x2 + 16x2 Combine like terms: -16x2 + 16x2 = 0 20 + -64x + 16x2 = 0 Factor out the Greatest Common Factor (GCF), '4'. 4(5 + -16x + 4x2) = 0 Ignore the factor 4.Subproblem 1
Set the factor '(5 + -16x + 4x2)' equal to zero and attempt to solve: Simplifying 5 + -16x + 4x2 = 0 Solving 5 + -16x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 1.25 + -4x + x2 = 0 Move the constant term to the right: Add '-1.25' to each side of the equation. 1.25 + -4x + -1.25 + x2 = 0 + -1.25 Reorder the terms: 1.25 + -1.25 + -4x + x2 = 0 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + -4x + x2 = 0 + -1.25 -4x + x2 = 0 + -1.25 Combine like terms: 0 + -1.25 = -1.25 -4x + x2 = -1.25 The x term is -4x. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4x + 4 + x2 = -1.25 + 4 Reorder the terms: 4 + -4x + x2 = -1.25 + 4 Combine like terms: -1.25 + 4 = 2.75 4 + -4x + x2 = 2.75 Factor a perfect square on the left side: (x + -2)(x + -2) = 2.75 Calculate the square root of the right side: 1.658312395 Break this problem into two subproblems by setting (x + -2) equal to 1.658312395 and -1.658312395.Subproblem 1
x + -2 = 1.658312395 Simplifying x + -2 = 1.658312395 Reorder the terms: -2 + x = 1.658312395 Solving -2 + x = 1.658312395 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + x = 1.658312395 + 2 Combine like terms: -2 + 2 = 0 0 + x = 1.658312395 + 2 x = 1.658312395 + 2 Combine like terms: 1.658312395 + 2 = 3.658312395 x = 3.658312395 Simplifying x = 3.658312395Subproblem 2
x + -2 = -1.658312395 Simplifying x + -2 = -1.658312395 Reorder the terms: -2 + x = -1.658312395 Solving -2 + x = -1.658312395 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + x = -1.658312395 + 2 Combine like terms: -2 + 2 = 0 0 + x = -1.658312395 + 2 x = -1.658312395 + 2 Combine like terms: -1.658312395 + 2 = 0.341687605 x = 0.341687605 Simplifying x = 0.341687605Solution
