Simplifying 2x2 + 5x + -30 = 0 Reorder the terms: -30 + 5x + 2x2 = 0 Solving -30 + 5x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -15 + 2.5x + x2 = 0 Move the constant term to the right: Add '15' to each side of the equation. -15 + 2.5x + 15 + x2 = 0 + 15 Reorder the terms: -15 + 15 + 2.5x + x2 = 0 + 15 Combine like terms: -15 + 15 = 0 0 + 2.5x + x2 = 0 + 15 2.5x + x2 = 0 + 15 Combine like terms: 0 + 15 = 15 2.5x + x2 = 15 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 = 15 + 1.5625 Reorder the terms: 1.5625 + 2.5x + x2 = 15 + 1.5625 Combine like terms: 15 + 1.5625 = 16.5625 1.5625 + 2.5x + x2 = 16.5625 Factor a perfect square on the left side: (x + 1.25)(x + 1.25) = 16.5625 Calculate the square root of the right side: 4.069705149 Break this problem into two subproblems by setting (x + 1.25) equal to 4.069705149 and -4.069705149.Subproblem 1
x + 1.25 = 4.069705149 Simplifying x + 1.25 = 4.069705149 Reorder the terms: 1.25 + x = 4.069705149 Solving 1.25 + x = 4.069705149 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 = 4.069705149 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = 4.069705149 + -1.25 x = 4.069705149 + -1.25 Combine like terms: 4.069705149 + -1.25 = 2.819705149 x = 2.819705149 Simplifying x = 2.819705149Subproblem 2
x + 1.25 = -4.069705149 Simplifying x + 1.25 = -4.069705149 Reorder the terms: 1.25 + x = -4.069705149 Solving 1.25 + x = -4.069705149 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 = -4.069705149 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = -4.069705149 + -1.25 x = -4.069705149 + -1.25 Combine like terms: -4.069705149 + -1.25 = -5.319705149 x = -5.319705149 Simplifying x = -5.319705149Solution
