Simplifying 50 = -16x2 + 96x + 60 Reorder the terms: 50 = 60 + 96x + -16x2 Solving 50 = 60 + 96x + -16x2 Solving for variable 'x'. Combine like terms: 50 + -60 = -10 -10 + -96x + 16x2 = 60 + 96x + -16x2 + -60 + -96x + 16x2 Reorder the terms: -10 + -96x + 16x2 = 60 + -60 + 96x + -96x + -16x2 + 16x2 Combine like terms: 60 + -60 = 0 -10 + -96x + 16x2 = 0 + 96x + -96x + -16x2 + 16x2 -10 + -96x + 16x2 = 96x + -96x + -16x2 + 16x2 Combine like terms: 96x + -96x = 0 -10 + -96x + 16x2 = 0 + -16x2 + 16x2 -10 + -96x + 16x2 = -16x2 + 16x2 Combine like terms: -16x2 + 16x2 = 0 -10 + -96x + 16x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-5 + -48x + 8x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-5 + -48x + 8x2)' equal to zero and attempt to solve: Simplifying -5 + -48x + 8x2 = 0 Solving -5 + -48x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -0.625 + -6x + x2 = 0 Move the constant term to the right: Add '0.625' to each side of the equation. -0.625 + -6x + 0.625 + x2 = 0 + 0.625 Reorder the terms: -0.625 + 0.625 + -6x + x2 = 0 + 0.625 Combine like terms: -0.625 + 0.625 = 0.000 0.000 + -6x + x2 = 0 + 0.625 -6x + x2 = 0 + 0.625 Combine like terms: 0 + 0.625 = 0.625 -6x + x2 = 0.625 The x term is -6x. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6x + 9 + x2 = 0.625 + 9 Reorder the terms: 9 + -6x + x2 = 0.625 + 9 Combine like terms: 0.625 + 9 = 9.625 9 + -6x + x2 = 9.625 Factor a perfect square on the left side: (x + -3)(x + -3) = 9.625 Calculate the square root of the right side: 3.102418411 Break this problem into two subproblems by setting (x + -3) equal to 3.102418411 and -3.102418411.Subproblem 1
x + -3 = 3.102418411 Simplifying x + -3 = 3.102418411 Reorder the terms: -3 + x = 3.102418411 Solving -3 + x = 3.102418411 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + x = 3.102418411 + 3 Combine like terms: -3 + 3 = 0 0 + x = 3.102418411 + 3 x = 3.102418411 + 3 Combine like terms: 3.102418411 + 3 = 6.102418411 x = 6.102418411 Simplifying x = 6.102418411Subproblem 2
x + -3 = -3.102418411 Simplifying x + -3 = -3.102418411 Reorder the terms: -3 + x = -3.102418411 Solving -3 + x = -3.102418411 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + x = -3.102418411 + 3 Combine like terms: -3 + 3 = 0 0 + x = -3.102418411 + 3 x = -3.102418411 + 3 Combine like terms: -3.102418411 + 3 = -0.102418411 x = -0.102418411 Simplifying x = -0.102418411Solution
