Simplifying 10 + 80x + -16x2 = 28 Solving 10 + 80x + -16x2 = 28 Solving for variable 'x'. Reorder the terms: 10 + -28 + 80x + -16x2 = 28 + -28 Combine like terms: 10 + -28 = -18 -18 + 80x + -16x2 = 28 + -28 Combine like terms: 28 + -28 = 0 -18 + 80x + -16x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-9 + 40x + -8x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-9 + 40x + -8x2)' equal to zero and attempt to solve: Simplifying -9 + 40x + -8x2 = 0 Solving -9 + 40x + -8x2 = 0 Begin completing the square. Divide all terms by -8 the coefficient of the squared term: Divide each side by '-8'. 1.125 + -5x + x2 = 0 Move the constant term to the right: Add '-1.125' to each side of the equation. 1.125 + -5x + -1.125 + x2 = 0 + -1.125 Reorder the terms: 1.125 + -1.125 + -5x + x2 = 0 + -1.125 Combine like terms: 1.125 + -1.125 = 0.000 0.000 + -5x + x2 = 0 + -1.125 -5x + x2 = 0 + -1.125 Combine like terms: 0 + -1.125 = -1.125 -5x + x2 = -1.125 The x term is -5x. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5x + 6.25 + x2 = -1.125 + 6.25 Reorder the terms: 6.25 + -5x + x2 = -1.125 + 6.25 Combine like terms: -1.125 + 6.25 = 5.125 6.25 + -5x + x2 = 5.125 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = 5.125 Calculate the square root of the right side: 2.263846285 Break this problem into two subproblems by setting (x + -2.5) equal to 2.263846285 and -2.263846285.Subproblem 1
