Simplifying 4x2 + 10x + -15 = 0 Reorder the terms: -15 + 10x + 4x2 = 0 Solving -15 + 10x + 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'. -3.75 + 2.5x + x2 = 0 Move the constant term to the right: Add '3.75' to each side of the equation. -3.75 + 2.5x + 3.75 + x2 = 0 + 3.75 Reorder the terms: -3.75 + 3.75 + 2.5x + x2 = 0 + 3.75 Combine like terms: -3.75 + 3.75 = 0.00 0.00 + 2.5x + x2 = 0 + 3.75 2.5x + x2 = 0 + 3.75 Combine like terms: 0 + 3.75 = 3.75 2.5x + x2 = 3.75 The x term is 2.5x. Take half its coefficient (1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. 2.5x + 1.5625 + x2 = 3.75 + 1.5625 Reorder the terms: 1.5625 + 2.5x + x2 = 3.75 + 1.5625 Combine like terms: 3.75 + 1.5625 = 5.3125 1.5625 + 2.5x + x2 = 5.3125 Factor a perfect square on the left side: (x + 1.25)(x + 1.25) = 5.3125 Calculate the square root of the right side: 2.304886114 Break this problem into two subproblems by setting (x + 1.25) equal to 2.304886114 and -2.304886114.Subproblem 1
x + 1.25 = 2.304886114 Simplifying x + 1.25 = 2.304886114 Reorder the terms: 1.25 + x = 2.304886114 Solving 1.25 + x = 2.304886114 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + x = 2.304886114 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = 2.304886114 + -1.25 x = 2.304886114 + -1.25 Combine like terms: 2.304886114 + -1.25 = 1.054886114 x = 1.054886114 Simplifying x = 1.054886114Subproblem 2
x + 1.25 = -2.304886114 Simplifying x + 1.25 = -2.304886114 Reorder the terms: 1.25 + x = -2.304886114 Solving 1.25 + x = -2.304886114 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + x = -2.304886114 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = -2.304886114 + -1.25 x = -2.304886114 + -1.25 Combine like terms: -2.304886114 + -1.25 = -3.554886114 x = -3.554886114 Simplifying x = -3.554886114Solution
