Simplifying 920 = -16x2 + 20x + 900 Reorder the terms: 920 = 900 + 20x + -16x2 Solving 920 = 900 + 20x + -16x2 Solving for variable 'x'. Combine like terms: 920 + -900 = 20 20 + -20x + 16x2 = 900 + 20x + -16x2 + -900 + -20x + 16x2 Reorder the terms: 20 + -20x + 16x2 = 900 + -900 + 20x + -20x + -16x2 + 16x2 Combine like terms: 900 + -900 = 0 20 + -20x + 16x2 = 0 + 20x + -20x + -16x2 + 16x2 20 + -20x + 16x2 = 20x + -20x + -16x2 + 16x2 Combine like terms: 20x + -20x = 0 20 + -20x + 16x2 = 0 + -16x2 + 16x2 20 + -20x + 16x2 = -16x2 + 16x2 Combine like terms: -16x2 + 16x2 = 0 20 + -20x + 16x2 = 0 Factor out the Greatest Common Factor (GCF), '4'. 4(5 + -5x + 4x2) = 0 Ignore the factor 4.Subproblem 1
Set the factor '(5 + -5x + 4x2)' equal to zero and attempt to solve: Simplifying 5 + -5x + 4x2 = 0 Solving 5 + -5x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 1.25 + -1.25x + x2 = 0 Move the constant term to the right: Add '-1.25' to each side of the equation. 1.25 + -1.25x + -1.25 + x2 = 0 + -1.25 Reorder the terms: 1.25 + -1.25 + -1.25x + x2 = 0 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + -1.25x + x2 = 0 + -1.25 -1.25x + x2 = 0 + -1.25 Combine like terms: 0 + -1.25 = -1.25 -1.25x + x2 = -1.25 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 = -1.25 + 0.390625 Reorder the terms: 0.390625 + -1.25x + x2 = -1.25 + 0.390625 Combine like terms: -1.25 + 0.390625 = -0.859375 0.390625 + -1.25x + x2 = -0.859375 Factor a perfect square on the left side: (x + -0.625)(x + -0.625) = -0.859375 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
