Simplifying 2x2 + 3x + -5 = 87 Reorder the terms: -5 + 3x + 2x2 = 87 Solving -5 + 3x + 2x2 = 87 Solving for variable 'x'. Reorder the terms: -5 + -87 + 3x + 2x2 = 87 + -87 Combine like terms: -5 + -87 = -92 -92 + 3x + 2x2 = 87 + -87 Combine like terms: 87 + -87 = 0 -92 + 3x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -46 + 1.5x + x2 = 0 Move the constant term to the right: Add '46' to each side of the equation. -46 + 1.5x + 46 + x2 = 0 + 46 Reorder the terms: -46 + 46 + 1.5x + x2 = 0 + 46 Combine like terms: -46 + 46 = 0 0 + 1.5x + x2 = 0 + 46 1.5x + x2 = 0 + 46 Combine like terms: 0 + 46 = 46 1.5x + x2 = 46 The x term is 1.5x. Take half its coefficient (0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. 1.5x + 0.5625 + x2 = 46 + 0.5625 Reorder the terms: 0.5625 + 1.5x + x2 = 46 + 0.5625 Combine like terms: 46 + 0.5625 = 46.5625 0.5625 + 1.5x + x2 = 46.5625 Factor a perfect square on the left side: (x + 0.75)(x + 0.75) = 46.5625 Calculate the square root of the right side: 6.823672032 Break this problem into two subproblems by setting (x + 0.75) equal to 6.823672032 and -6.823672032.Subproblem 1
x + 0.75 = 6.823672032 Simplifying x + 0.75 = 6.823672032 Reorder the terms: 0.75 + x = 6.823672032 Solving 0.75 + x = 6.823672032 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + x = 6.823672032 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + x = 6.823672032 + -0.75 x = 6.823672032 + -0.75 Combine like terms: 6.823672032 + -0.75 = 6.073672032 x = 6.073672032 Simplifying x = 6.073672032Subproblem 2
x + 0.75 = -6.823672032 Simplifying x + 0.75 = -6.823672032 Reorder the terms: 0.75 + x = -6.823672032 Solving 0.75 + x = -6.823672032 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + x = -6.823672032 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + x = -6.823672032 + -0.75 x = -6.823672032 + -0.75 Combine like terms: -6.823672032 + -0.75 = -7.573672032 x = -7.573672032 Simplifying x = -7.573672032Solution
