Simplifying 2x2 + -5x = 142 Reorder the terms: -5x + 2x2 = 142 Solving -5x + 2x2 = 142 Solving for variable 'x'. Reorder the terms: -142 + -5x + 2x2 = 142 + -142 Combine like terms: 142 + -142 = 0 -142 + -5x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -71 + -2.5x + x2 = 0 Move the constant term to the right: Add '71' to each side of the equation. -71 + -2.5x + 71 + x2 = 0 + 71 Reorder the terms: -71 + 71 + -2.5x + x2 = 0 + 71 Combine like terms: -71 + 71 = 0 0 + -2.5x + x2 = 0 + 71 -2.5x + x2 = 0 + 71 Combine like terms: 0 + 71 = 71 -2.5x + x2 = 71 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 = 71 + 1.5625 Reorder the terms: 1.5625 + -2.5x + x2 = 71 + 1.5625 Combine like terms: 71 + 1.5625 = 72.5625 1.5625 + -2.5x + x2 = 72.5625 Factor a perfect square on the left side: (x + -1.25)(x + -1.25) = 72.5625 Calculate the square root of the right side: 8.518362519 Break this problem into two subproblems by setting (x + -1.25) equal to 8.518362519 and -8.518362519.Subproblem 1
x + -1.25 = 8.518362519 Simplifying x + -1.25 = 8.518362519 Reorder the terms: -1.25 + x = 8.518362519 Solving -1.25 + x = 8.518362519 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 = 8.518362519 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + x = 8.518362519 + 1.25 x = 8.518362519 + 1.25 Combine like terms: 8.518362519 + 1.25 = 9.768362519 x = 9.768362519 Simplifying x = 9.768362519Subproblem 2
x + -1.25 = -8.518362519 Simplifying x + -1.25 = -8.518362519 Reorder the terms: -1.25 + x = -8.518362519 Solving -1.25 + x = -8.518362519 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 = -8.518362519 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + x = -8.518362519 + 1.25 x = -8.518362519 + 1.25 Combine like terms: -8.518362519 + 1.25 = -7.268362519 x = -7.268362519 Simplifying x = -7.268362519Solution
