Simplifying 2x2 + 7x + -83 = 0 Reorder the terms: -83 + 7x + 2x2 = 0 Solving -83 + 7x + 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'. -41.5 + 3.5x + x2 = 0 Move the constant term to the right: Add '41.5' to each side of the equation. -41.5 + 3.5x + 41.5 + x2 = 0 + 41.5 Reorder the terms: -41.5 + 41.5 + 3.5x + x2 = 0 + 41.5 Combine like terms: -41.5 + 41.5 = 0.0 0.0 + 3.5x + x2 = 0 + 41.5 3.5x + x2 = 0 + 41.5 Combine like terms: 0 + 41.5 = 41.5 3.5x + x2 = 41.5 The x term is 3.5x. Take half its coefficient (1.75). Square it (3.0625) and add it to both sides. Add '3.0625' to each side of the equation. 3.5x + 3.0625 + x2 = 41.5 + 3.0625 Reorder the terms: 3.0625 + 3.5x + x2 = 41.5 + 3.0625 Combine like terms: 41.5 + 3.0625 = 44.5625 3.0625 + 3.5x + x2 = 44.5625 Factor a perfect square on the left side: (x + 1.75)(x + 1.75) = 44.5625 Calculate the square root of the right side: 6.675514961 Break this problem into two subproblems by setting (x + 1.75) equal to 6.675514961 and -6.675514961.Subproblem 1
x + 1.75 = 6.675514961 Simplifying x + 1.75 = 6.675514961 Reorder the terms: 1.75 + x = 6.675514961 Solving 1.75 + x = 6.675514961 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.75' to each side of the equation. 1.75 + -1.75 + x = 6.675514961 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + x = 6.675514961 + -1.75 x = 6.675514961 + -1.75 Combine like terms: 6.675514961 + -1.75 = 4.925514961 x = 4.925514961 Simplifying x = 4.925514961Subproblem 2
x + 1.75 = -6.675514961 Simplifying x + 1.75 = -6.675514961 Reorder the terms: 1.75 + x = -6.675514961 Solving 1.75 + x = -6.675514961 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.75' to each side of the equation. 1.75 + -1.75 + x = -6.675514961 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + x = -6.675514961 + -1.75 x = -6.675514961 + -1.75 Combine like terms: -6.675514961 + -1.75 = -8.425514961 x = -8.425514961 Simplifying x = -8.425514961Solution
