Simplifying 80 = 76x + -16x2 Solving 80 = 76x + -16x2 Solving for variable 'x'. Reorder the terms: 80 + -76x + 16x2 = 76x + -76x + -16x2 + 16x2 Combine like terms: 76x + -76x = 0 80 + -76x + 16x2 = 0 + -16x2 + 16x2 80 + -76x + 16x2 = -16x2 + 16x2 Combine like terms: -16x2 + 16x2 = 0 80 + -76x + 16x2 = 0 Factor out the Greatest Common Factor (GCF), '4'. 4(20 + -19x + 4x2) = 0 Ignore the factor 4.Subproblem 1
Set the factor '(20 + -19x + 4x2)' equal to zero and attempt to solve: Simplifying 20 + -19x + 4x2 = 0 Solving 20 + -19x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 5 + -4.75x + x2 = 0 Move the constant term to the right: Add '-5' to each side of the equation. 5 + -4.75x + -5 + x2 = 0 + -5 Reorder the terms: 5 + -5 + -4.75x + x2 = 0 + -5 Combine like terms: 5 + -5 = 0 0 + -4.75x + x2 = 0 + -5 -4.75x + x2 = 0 + -5 Combine like terms: 0 + -5 = -5 -4.75x + x2 = -5 The x term is -4.75x. Take half its coefficient (-2.375). Square it (5.640625) and add it to both sides. Add '5.640625' to each side of the equation. -4.75x + 5.640625 + x2 = -5 + 5.640625 Reorder the terms: 5.640625 + -4.75x + x2 = -5 + 5.640625 Combine like terms: -5 + 5.640625 = 0.640625 5.640625 + -4.75x + x2 = 0.640625 Factor a perfect square on the left side: (x + -2.375)(x + -2.375) = 0.640625 Calculate the square root of the right side: 0.80039053 Break this problem into two subproblems by setting (x + -2.375) equal to 0.80039053 and -0.80039053.Subproblem 1
x + -2.375 = 0.80039053 Simplifying x + -2.375 = 0.80039053 Reorder the terms: -2.375 + x = 0.80039053 Solving -2.375 + x = 0.80039053 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.375' to each side of the equation. -2.375 + 2.375 + x = 0.80039053 + 2.375 Combine like terms: -2.375 + 2.375 = 0.000 0.000 + x = 0.80039053 + 2.375 x = 0.80039053 + 2.375 Combine like terms: 0.80039053 + 2.375 = 3.17539053 x = 3.17539053 Simplifying x = 3.17539053Subproblem 2
x + -2.375 = -0.80039053 Simplifying x + -2.375 = -0.80039053 Reorder the terms: -2.375 + x = -0.80039053 Solving -2.375 + x = -0.80039053 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.375' to each side of the equation. -2.375 + 2.375 + x = -0.80039053 + 2.375 Combine like terms: -2.375 + 2.375 = 0.000 0.000 + x = -0.80039053 + 2.375 x = -0.80039053 + 2.375 Combine like terms: -0.80039053 + 2.375 = 1.57460947 x = 1.57460947 Simplifying x = 1.57460947Solution
