Simplifying 50 = -16x2 + 4x + 90 Reorder the terms: 50 = 90 + 4x + -16x2 Solving 50 = 90 + 4x + -16x2 Solving for variable 'x'. Combine like terms: 50 + -90 = -40 -40 + -4x + 16x2 = 90 + 4x + -16x2 + -90 + -4x + 16x2 Reorder the terms: -40 + -4x + 16x2 = 90 + -90 + 4x + -4x + -16x2 + 16x2 Combine like terms: 90 + -90 = 0 -40 + -4x + 16x2 = 0 + 4x + -4x + -16x2 + 16x2 -40 + -4x + 16x2 = 4x + -4x + -16x2 + 16x2 Combine like terms: 4x + -4x = 0 -40 + -4x + 16x2 = 0 + -16x2 + 16x2 -40 + -4x + 16x2 = -16x2 + 16x2 Combine like terms: -16x2 + 16x2 = 0 -40 + -4x + 16x2 = 0 Factor out the Greatest Common Factor (GCF), '4'. 4(-10 + -1x + 4x2) = 0 Ignore the factor 4.Subproblem 1
Set the factor '(-10 + -1x + 4x2)' equal to zero and attempt to solve: Simplifying -10 + -1x + 4x2 = 0 Solving -10 + -1x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -2.5 + -0.25x + x2 = 0 Move the constant term to the right: Add '2.5' to each side of the equation. -2.5 + -0.25x + 2.5 + x2 = 0 + 2.5 Reorder the terms: -2.5 + 2.5 + -0.25x + x2 = 0 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + -0.25x + x2 = 0 + 2.5 -0.25x + x2 = 0 + 2.5 Combine like terms: 0 + 2.5 = 2.5 -0.25x + x2 = 2.5 The x term is -0.25x. Take half its coefficient (-0.125). Square it (0.015625) and add it to both sides. Add '0.015625' to each side of the equation. -0.25x + 0.015625 + x2 = 2.5 + 0.015625 Reorder the terms: 0.015625 + -0.25x + x2 = 2.5 + 0.015625 Combine like terms: 2.5 + 0.015625 = 2.515625 0.015625 + -0.25x + x2 = 2.515625 Factor a perfect square on the left side: (x + -0.125)(x + -0.125) = 2.515625 Calculate the square root of the right side: 1.586072193 Break this problem into two subproblems by setting (x + -0.125) equal to 1.586072193 and -1.586072193.Subproblem 1
x + -0.125 = 1.586072193 Simplifying x + -0.125 = 1.586072193 Reorder the terms: -0.125 + x = 1.586072193 Solving -0.125 + x = 1.586072193 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.125' to each side of the equation. -0.125 + 0.125 + x = 1.586072193 + 0.125 Combine like terms: -0.125 + 0.125 = 0.000 0.000 + x = 1.586072193 + 0.125 x = 1.586072193 + 0.125 Combine like terms: 1.586072193 + 0.125 = 1.711072193 x = 1.711072193 Simplifying x = 1.711072193Subproblem 2
x + -0.125 = -1.586072193 Simplifying x + -0.125 = -1.586072193 Reorder the terms: -0.125 + x = -1.586072193 Solving -0.125 + x = -1.586072193 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.125' to each side of the equation. -0.125 + 0.125 + x = -1.586072193 + 0.125 Combine like terms: -0.125 + 0.125 = 0.000 0.000 + x = -1.586072193 + 0.125 x = -1.586072193 + 0.125 Combine like terms: -1.586072193 + 0.125 = -1.461072193 x = -1.461072193 Simplifying x = -1.461072193Solution
