Simplifying 2x(x + 4) = 2x + 5 Reorder the terms: 2x(4 + x) = 2x + 5 (4 * 2x + x * 2x) = 2x + 5 (8x + 2x2) = 2x + 5 Reorder the terms: 8x + 2x2 = 5 + 2x Solving 8x + 2x2 = 5 + 2x Solving for variable 'x'. Reorder the terms: -5 + 8x + -2x + 2x2 = 5 + 2x + -5 + -2x Combine like terms: 8x + -2x = 6x -5 + 6x + 2x2 = 5 + 2x + -5 + -2x Reorder the terms: -5 + 6x + 2x2 = 5 + -5 + 2x + -2x Combine like terms: 5 + -5 = 0 -5 + 6x + 2x2 = 0 + 2x + -2x -5 + 6x + 2x2 = 2x + -2x Combine like terms: 2x + -2x = 0 -5 + 6x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -2.5 + 3x + x2 = 0 Move the constant term to the right: Add '2.5' to each side of the equation. -2.5 + 3x + 2.5 + x2 = 0 + 2.5 Reorder the terms: -2.5 + 2.5 + 3x + x2 = 0 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + 3x + x2 = 0 + 2.5 3x + x2 = 0 + 2.5 Combine like terms: 0 + 2.5 = 2.5 3x + x2 = 2.5 The x term is 3x. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3x + 2.25 + x2 = 2.5 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 2.5 + 2.25 Combine like terms: 2.5 + 2.25 = 4.75 2.25 + 3x + x2 = 4.75 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 4.75 Calculate the square root of the right side: 2.179449472 Break this problem into two subproblems by setting (x + 1.5) equal to 2.179449472 and -2.179449472.Subproblem 1
x + 1.5 = 2.179449472 Simplifying x + 1.5 = 2.179449472 Reorder the terms: 1.5 + x = 2.179449472 Solving 1.5 + x = 2.179449472 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = 2.179449472 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 2.179449472 + -1.5 x = 2.179449472 + -1.5 Combine like terms: 2.179449472 + -1.5 = 0.679449472 x = 0.679449472 Simplifying x = 0.679449472Subproblem 2
x + 1.5 = -2.179449472 Simplifying x + 1.5 = -2.179449472 Reorder the terms: 1.5 + x = -2.179449472 Solving 1.5 + x = -2.179449472 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = -2.179449472 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -2.179449472 + -1.5 x = -2.179449472 + -1.5 Combine like terms: -2.179449472 + -1.5 = -3.679449472 x = -3.679449472 Simplifying x = -3.679449472Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.679449472, -3.679449472}
