Simplifying 4x(5x + 4) = 155 Reorder the terms: 4x(4 + 5x) = 155 (4 * 4x + 5x * 4x) = 155 (16x + 20x2) = 155 Solving 16x + 20x2 = 155 Solving for variable 'x'. Reorder the terms: -155 + 16x + 20x2 = 155 + -155 Combine like terms: 155 + -155 = 0 -155 + 16x + 20x2 = 0 Begin completing the square. Divide all terms by 20 the coefficient of the squared term: Divide each side by '20'. -7.75 + 0.8x + x2 = 0.0 Move the constant term to the right: Add '7.75' to each side of the equation. -7.75 + 0.8x + 7.75 + x2 = 0.0 + 7.75 Reorder the terms: -7.75 + 7.75 + 0.8x + x2 = 0.0 + 7.75 Combine like terms: -7.75 + 7.75 = 0.00 0.00 + 0.8x + x2 = 0.0 + 7.75 0.8x + x2 = 0.0 + 7.75 Combine like terms: 0.0 + 7.75 = 7.75 0.8x + x2 = 7.75 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 = 7.75 + 0.16 Reorder the terms: 0.16 + 0.8x + x2 = 7.75 + 0.16 Combine like terms: 7.75 + 0.16 = 7.91 0.16 + 0.8x + x2 = 7.91 Factor a perfect square on the left side: (x + 0.4)(x + 0.4) = 7.91 Calculate the square root of the right side: 2.812472222 Break this problem into two subproblems by setting (x + 0.4) equal to 2.812472222 and -2.812472222.Subproblem 1
x + 0.4 = 2.812472222 Simplifying x + 0.4 = 2.812472222 Reorder the terms: 0.4 + x = 2.812472222 Solving 0.4 + x = 2.812472222 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 = 2.812472222 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + x = 2.812472222 + -0.4 x = 2.812472222 + -0.4 Combine like terms: 2.812472222 + -0.4 = 2.412472222 x = 2.412472222 Simplifying x = 2.412472222Subproblem 2
x + 0.4 = -2.812472222 Simplifying x + 0.4 = -2.812472222 Reorder the terms: 0.4 + x = -2.812472222 Solving 0.4 + x = -2.812472222 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 = -2.812472222 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + x = -2.812472222 + -0.4 x = -2.812472222 + -0.4 Combine like terms: -2.812472222 + -0.4 = -3.212472222 x = -3.212472222 Simplifying x = -3.212472222Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.412472222, -3.212472222}
