Simplifying 2x2 + 3x = 256 Reorder the terms: 3x + 2x2 = 256 Solving 3x + 2x2 = 256 Solving for variable 'x'. Reorder the terms: -256 + 3x + 2x2 = 256 + -256 Combine like terms: 256 + -256 = 0 -256 + 3x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -128 + 1.5x + x2 = 0 Move the constant term to the right: Add '128' to each side of the equation. -128 + 1.5x + 128 + x2 = 0 + 128 Reorder the terms: -128 + 128 + 1.5x + x2 = 0 + 128 Combine like terms: -128 + 128 = 0 0 + 1.5x + x2 = 0 + 128 1.5x + x2 = 0 + 128 Combine like terms: 0 + 128 = 128 1.5x + x2 = 128 The x term is 1.5x. Take half its coefficient (0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. 1.5x + 0.5625 + x2 = 128 + 0.5625 Reorder the terms: 0.5625 + 1.5x + x2 = 128 + 0.5625 Combine like terms: 128 + 0.5625 = 128.5625 0.5625 + 1.5x + x2 = 128.5625 Factor a perfect square on the left side: (x + 0.75)(x + 0.75) = 128.5625 Calculate the square root of the right side: 11.33854047 Break this problem into two subproblems by setting (x + 0.75) equal to 11.33854047 and -11.33854047.Subproblem 1
x + 0.75 = 11.33854047 Simplifying x + 0.75 = 11.33854047 Reorder the terms: 0.75 + x = 11.33854047 Solving 0.75 + x = 11.33854047 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + x = 11.33854047 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + x = 11.33854047 + -0.75 x = 11.33854047 + -0.75 Combine like terms: 11.33854047 + -0.75 = 10.58854047 x = 10.58854047 Simplifying x = 10.58854047Subproblem 2
x + 0.75 = -11.33854047 Simplifying x + 0.75 = -11.33854047 Reorder the terms: 0.75 + x = -11.33854047 Solving 0.75 + x = -11.33854047 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + x = -11.33854047 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + x = -11.33854047 + -0.75 x = -11.33854047 + -0.75 Combine like terms: -11.33854047 + -0.75 = -12.08854047 x = -12.08854047 Simplifying x = -12.08854047Solution
