Simplifying 5x2 + 4x + -128 = 0 Reorder the terms: -128 + 4x + 5x2 = 0 Solving -128 + 4x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -25.6 + 0.8x + x2 = 0 Move the constant term to the right: Add '25.6' to each side of the equation. -25.6 + 0.8x + 25.6 + x2 = 0 + 25.6 Reorder the terms: -25.6 + 25.6 + 0.8x + x2 = 0 + 25.6 Combine like terms: -25.6 + 25.6 = 0.0 0.0 + 0.8x + x2 = 0 + 25.6 0.8x + x2 = 0 + 25.6 Combine like terms: 0 + 25.6 = 25.6 0.8x + x2 = 25.6 The x term is 0.8x. Take half its coefficient (0.4). Square it (0.16) and add it to both sides. Add '0.16' to each side of the equation. 0.8x + 0.16 + x2 = 25.6 + 0.16 Reorder the terms: 0.16 + 0.8x + x2 = 25.6 + 0.16 Combine like terms: 25.6 + 0.16 = 25.76 0.16 + 0.8x + x2 = 25.76 Factor a perfect square on the left side: (x + 0.4)(x + 0.4) = 25.76 Calculate the square root of the right side: 5.075431016 Break this problem into two subproblems by setting (x + 0.4) equal to 5.075431016 and -5.075431016.Subproblem 1
x + 0.4 = 5.075431016 Simplifying x + 0.4 = 5.075431016 Reorder the terms: 0.4 + x = 5.075431016 Solving 0.4 + x = 5.075431016 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.4' to each side of the equation. 0.4 + -0.4 + x = 5.075431016 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + x = 5.075431016 + -0.4 x = 5.075431016 + -0.4 Combine like terms: 5.075431016 + -0.4 = 4.675431016 x = 4.675431016 Simplifying x = 4.675431016Subproblem 2
x + 0.4 = -5.075431016 Simplifying x + 0.4 = -5.075431016 Reorder the terms: 0.4 + x = -5.075431016 Solving 0.4 + x = -5.075431016 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.4' to each side of the equation. 0.4 + -0.4 + x = -5.075431016 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + x = -5.075431016 + -0.4 x = -5.075431016 + -0.4 Combine like terms: -5.075431016 + -0.4 = -5.475431016 x = -5.475431016 Simplifying x = -5.475431016Solution
