Simplifying x2 + 3x + 4 + x2 + 2x + -6 = 0 Reorder the terms: 4 + -6 + 3x + 2x + x2 + x2 = 0 Combine like terms: 4 + -6 = -2 -2 + 3x + 2x + x2 + x2 = 0 Combine like terms: 3x + 2x = 5x -2 + 5x + x2 + x2 = 0 Combine like terms: x2 + x2 = 2x2 -2 + 5x + 2x2 = 0 Solving -2 + 5x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -1 + 2.5x + x2 = 0 Move the constant term to the right: Add '1' to each side of the equation. -1 + 2.5x + 1 + x2 = 0 + 1 Reorder the terms: -1 + 1 + 2.5x + x2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + 2.5x + x2 = 0 + 1 2.5x + x2 = 0 + 1 Combine like terms: 0 + 1 = 1 2.5x + x2 = 1 The x term is 2.5x. Take half its coefficient (1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. 2.5x + 1.5625 + x2 = 1 + 1.5625 Reorder the terms: 1.5625 + 2.5x + x2 = 1 + 1.5625 Combine like terms: 1 + 1.5625 = 2.5625 1.5625 + 2.5x + x2 = 2.5625 Factor a perfect square on the left side: (x + 1.25)(x + 1.25) = 2.5625 Calculate the square root of the right side: 1.600781059 Break this problem into two subproblems by setting (x + 1.25) equal to 1.600781059 and -1.600781059.Subproblem 1
x + 1.25 = 1.600781059 Simplifying x + 1.25 = 1.600781059 Reorder the terms: 1.25 + x = 1.600781059 Solving 1.25 + x = 1.600781059 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + x = 1.600781059 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = 1.600781059 + -1.25 x = 1.600781059 + -1.25 Combine like terms: 1.600781059 + -1.25 = 0.350781059 x = 0.350781059 Simplifying x = 0.350781059Subproblem 2
x + 1.25 = -1.600781059 Simplifying x + 1.25 = -1.600781059 Reorder the terms: 1.25 + x = -1.600781059 Solving 1.25 + x = -1.600781059 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + x = -1.600781059 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = -1.600781059 + -1.25 x = -1.600781059 + -1.25 Combine like terms: -1.600781059 + -1.25 = -2.850781059 x = -2.850781059 Simplifying x = -2.850781059Solution
