Simplifying 4x2 + -60x + -65 = 0 Reorder the terms: -65 + -60x + 4x2 = 0 Solving -65 + -60x + 4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -16.25 + -15x + x2 = 0 Move the constant term to the right: Add '16.25' to each side of the equation. -16.25 + -15x + 16.25 + x2 = 0 + 16.25 Reorder the terms: -16.25 + 16.25 + -15x + x2 = 0 + 16.25 Combine like terms: -16.25 + 16.25 = 0.00 0.00 + -15x + x2 = 0 + 16.25 -15x + x2 = 0 + 16.25 Combine like terms: 0 + 16.25 = 16.25 -15x + x2 = 16.25 The x term is -15x. Take half its coefficient (-7.5). Square it (56.25) and add it to both sides. Add '56.25' to each side of the equation. -15x + 56.25 + x2 = 16.25 + 56.25 Reorder the terms: 56.25 + -15x + x2 = 16.25 + 56.25 Combine like terms: 16.25 + 56.25 = 72.5 56.25 + -15x + x2 = 72.5 Factor a perfect square on the left side: (x + -7.5)(x + -7.5) = 72.5 Calculate the square root of the right side: 8.514693183 Break this problem into two subproblems by setting (x + -7.5) equal to 8.514693183 and -8.514693183.Subproblem 1
x + -7.5 = 8.514693183 Simplifying x + -7.5 = 8.514693183 Reorder the terms: -7.5 + x = 8.514693183 Solving -7.5 + x = 8.514693183 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '7.5' to each side of the equation. -7.5 + 7.5 + x = 8.514693183 + 7.5 Combine like terms: -7.5 + 7.5 = 0.0 0.0 + x = 8.514693183 + 7.5 x = 8.514693183 + 7.5 Combine like terms: 8.514693183 + 7.5 = 16.014693183 x = 16.014693183 Simplifying x = 16.014693183Subproblem 2
x + -7.5 = -8.514693183 Simplifying x + -7.5 = -8.514693183 Reorder the terms: -7.5 + x = -8.514693183 Solving -7.5 + x = -8.514693183 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '7.5' to each side of the equation. -7.5 + 7.5 + x = -8.514693183 + 7.5 Combine like terms: -7.5 + 7.5 = 0.0 0.0 + x = -8.514693183 + 7.5 x = -8.514693183 + 7.5 Combine like terms: -8.514693183 + 7.5 = -1.014693183 x = -1.014693183 Simplifying x = -1.014693183Solution
