Simplifying 2x(x + 1) = 3x + 4 Reorder the terms: 2x(1 + x) = 3x + 4 (1 * 2x + x * 2x) = 3x + 4 (2x + 2x2) = 3x + 4 Reorder the terms: 2x + 2x2 = 4 + 3x Solving 2x + 2x2 = 4 + 3x Solving for variable 'x'. Reorder the terms: -4 + 2x + -3x + 2x2 = 4 + 3x + -4 + -3x Combine like terms: 2x + -3x = -1x -4 + -1x + 2x2 = 4 + 3x + -4 + -3x Reorder the terms: -4 + -1x + 2x2 = 4 + -4 + 3x + -3x Combine like terms: 4 + -4 = 0 -4 + -1x + 2x2 = 0 + 3x + -3x -4 + -1x + 2x2 = 3x + -3x Combine like terms: 3x + -3x = 0 -4 + -1x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -2 + -0.5x + x2 = 0 Move the constant term to the right: Add '2' to each side of the equation. -2 + -0.5x + 2 + x2 = 0 + 2 Reorder the terms: -2 + 2 + -0.5x + x2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + -0.5x + x2 = 0 + 2 -0.5x + x2 = 0 + 2 Combine like terms: 0 + 2 = 2 -0.5x + x2 = 2 The x term is -0.5x. Take half its coefficient (-0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. -0.5x + 0.0625 + x2 = 2 + 0.0625 Reorder the terms: 0.0625 + -0.5x + x2 = 2 + 0.0625 Combine like terms: 2 + 0.0625 = 2.0625 0.0625 + -0.5x + x2 = 2.0625 Factor a perfect square on the left side: (x + -0.25)(x + -0.25) = 2.0625 Calculate the square root of the right side: 1.436140662 Break this problem into two subproblems by setting (x + -0.25) equal to 1.436140662 and -1.436140662.Subproblem 1
x + -0.25 = 1.436140662 Simplifying x + -0.25 = 1.436140662 Reorder the terms: -0.25 + x = 1.436140662 Solving -0.25 + x = 1.436140662 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + x = 1.436140662 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + x = 1.436140662 + 0.25 x = 1.436140662 + 0.25 Combine like terms: 1.436140662 + 0.25 = 1.686140662 x = 1.686140662 Simplifying x = 1.686140662Subproblem 2
x + -0.25 = -1.436140662 Simplifying x + -0.25 = -1.436140662 Reorder the terms: -0.25 + x = -1.436140662 Solving -0.25 + x = -1.436140662 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + x = -1.436140662 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + x = -1.436140662 + 0.25 x = -1.436140662 + 0.25 Combine like terms: -1.436140662 + 0.25 = -1.186140662 x = -1.186140662 Simplifying x = -1.186140662Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.686140662, -1.186140662}
