Simplifying 2x(x + 2) = x + 3 Reorder the terms: 2x(2 + x) = x + 3 (2 * 2x + x * 2x) = x + 3 (4x + 2x2) = x + 3 Reorder the terms: 4x + 2x2 = 3 + x Solving 4x + 2x2 = 3 + x Solving for variable 'x'. Reorder the terms: -3 + 4x + -1x + 2x2 = 3 + x + -3 + -1x Combine like terms: 4x + -1x = 3x -3 + 3x + 2x2 = 3 + x + -3 + -1x Reorder the terms: -3 + 3x + 2x2 = 3 + -3 + x + -1x Combine like terms: 3 + -3 = 0 -3 + 3x + 2x2 = 0 + x + -1x -3 + 3x + 2x2 = x + -1x Combine like terms: x + -1x = 0 -3 + 3x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -1.5 + 1.5x + x2 = 0 Move the constant term to the right: Add '1.5' to each side of the equation. -1.5 + 1.5x + 1.5 + x2 = 0 + 1.5 Reorder the terms: -1.5 + 1.5 + 1.5x + x2 = 0 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + 1.5x + x2 = 0 + 1.5 1.5x + x2 = 0 + 1.5 Combine like terms: 0 + 1.5 = 1.5 1.5x + x2 = 1.5 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 = 1.5 + 0.5625 Reorder the terms: 0.5625 + 1.5x + x2 = 1.5 + 0.5625 Combine like terms: 1.5 + 0.5625 = 2.0625 0.5625 + 1.5x + x2 = 2.0625 Factor a perfect square on the left side: (x + 0.75)(x + 0.75) = 2.0625 Calculate the square root of the right side: 1.436140662 Break this problem into two subproblems by setting (x + 0.75) equal to 1.436140662 and -1.436140662.Subproblem 1
x + 0.75 = 1.436140662 Simplifying x + 0.75 = 1.436140662 Reorder the terms: 0.75 + x = 1.436140662 Solving 0.75 + x = 1.436140662 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 = 1.436140662 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + x = 1.436140662 + -0.75 x = 1.436140662 + -0.75 Combine like terms: 1.436140662 + -0.75 = 0.686140662 x = 0.686140662 Simplifying x = 0.686140662Subproblem 2
x + 0.75 = -1.436140662 Simplifying x + 0.75 = -1.436140662 Reorder the terms: 0.75 + x = -1.436140662 Solving 0.75 + x = -1.436140662 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 = -1.436140662 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + x = -1.436140662 + -0.75 x = -1.436140662 + -0.75 Combine like terms: -1.436140662 + -0.75 = -2.186140662 x = -2.186140662 Simplifying x = -2.186140662Solution
