Simplifying 2x2 + -5x = 288 Reorder the terms: -5x + 2x2 = 288 Solving -5x + 2x2 = 288 Solving for variable 'x'. Reorder the terms: -288 + -5x + 2x2 = 288 + -288 Combine like terms: 288 + -288 = 0 -288 + -5x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -144 + -2.5x + x2 = 0 Move the constant term to the right: Add '144' to each side of the equation. -144 + -2.5x + 144 + x2 = 0 + 144 Reorder the terms: -144 + 144 + -2.5x + x2 = 0 + 144 Combine like terms: -144 + 144 = 0 0 + -2.5x + x2 = 0 + 144 -2.5x + x2 = 0 + 144 Combine like terms: 0 + 144 = 144 -2.5x + x2 = 144 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 = 144 + 1.5625 Reorder the terms: 1.5625 + -2.5x + x2 = 144 + 1.5625 Combine like terms: 144 + 1.5625 = 145.5625 1.5625 + -2.5x + x2 = 145.5625 Factor a perfect square on the left side: (x + -1.25)(x + -1.25) = 145.5625 Calculate the square root of the right side: 12.064928512 Break this problem into two subproblems by setting (x + -1.25) equal to 12.064928512 and -12.064928512.Subproblem 1
x + -1.25 = 12.064928512 Simplifying x + -1.25 = 12.064928512 Reorder the terms: -1.25 + x = 12.064928512 Solving -1.25 + x = 12.064928512 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 = 12.064928512 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + x = 12.064928512 + 1.25 x = 12.064928512 + 1.25 Combine like terms: 12.064928512 + 1.25 = 13.314928512 x = 13.314928512 Simplifying x = 13.314928512Subproblem 2
x + -1.25 = -12.064928512 Simplifying x + -1.25 = -12.064928512 Reorder the terms: -1.25 + x = -12.064928512 Solving -1.25 + x = -12.064928512 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 = -12.064928512 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + x = -12.064928512 + 1.25 x = -12.064928512 + 1.25 Combine like terms: -12.064928512 + 1.25 = -10.814928512 x = -10.814928512 Simplifying x = -10.814928512Solution
