Simplifying (x + 2)(x + -1) = 6.75 Reorder the terms: (2 + x)(x + -1) = 6.75 Reorder the terms: (2 + x)(-1 + x) = 6.75 Multiply (2 + x) * (-1 + x) (2(-1 + x) + x(-1 + x)) = 6.75 ((-1 * 2 + x * 2) + x(-1 + x)) = 6.75 ((-2 + 2x) + x(-1 + x)) = 6.75 (-2 + 2x + (-1 * x + x * x)) = 6.75 (-2 + 2x + (-1x + x2)) = 6.75 Combine like terms: 2x + -1x = 1x (-2 + 1x + x2) = 6.75 Solving -2 + 1x + x2 = 6.75 Solving for variable 'x'. Reorder the terms: -2 + -6.75 + 1x + x2 = 6.75 + -6.75 Combine like terms: -2 + -6.75 = -8.75 -8.75 + 1x + x2 = 6.75 + -6.75 Combine like terms: 6.75 + -6.75 = 0.00 -8.75 + 1x + x2 = 0.00 Begin completing the square. Move the constant term to the right: Add '8.75' to each side of the equation. -8.75 + 1x + 8.75 + x2 = 0.00 + 8.75 Reorder the terms: -8.75 + 8.75 + 1x + x2 = 0.00 + 8.75 Combine like terms: -8.75 + 8.75 = 0.00 0.00 + 1x + x2 = 0.00 + 8.75 1x + x2 = 0.00 + 8.75 Combine like terms: 0.00 + 8.75 = 8.75 1x + x2 = 8.75 The x term is 1x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. x + 0.25 + x2 = 8.75 + 0.25 Reorder the terms: 0.25 + x + x2 = 8.75 + 0.25 Combine like terms: 8.75 + 0.25 = 9 0.25 + x + x2 = 9 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 9 Calculate the square root of the right side: 3 Break this problem into two subproblems by setting (x + 0.5) equal to 3 and -3.Subproblem 1
x + 0.5 = 3 Simplifying x + 0.5 = 3 Reorder the terms: 0.5 + x = 3 Solving 0.5 + x = 3 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = 3 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 3 + -0.5 x = 3 + -0.5 Combine like terms: 3 + -0.5 = 2.5 x = 2.5 Simplifying x = 2.5Subproblem 2
x + 0.5 = -3 Simplifying x + 0.5 = -3 Reorder the terms: 0.5 + x = -3 Solving 0.5 + x = -3 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = -3 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -3 + -0.5 x = -3 + -0.5 Combine like terms: -3 + -0.5 = -3.5 x = -3.5 Simplifying x = -3.5Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.5, -3.5}
