Simplifying (2x + 1)(4 + -1x) = 10 + -1(2x * 2x) Reorder the terms: (1 + 2x)(4 + -1x) = 10 + -1(2x * 2x) Multiply (1 + 2x) * (4 + -1x) (1(4 + -1x) + 2x * (4 + -1x)) = 10 + -1(2x * 2x) ((4 * 1 + -1x * 1) + 2x * (4 + -1x)) = 10 + -1(2x * 2x) ((4 + -1x) + 2x * (4 + -1x)) = 10 + -1(2x * 2x) (4 + -1x + (4 * 2x + -1x * 2x)) = 10 + -1(2x * 2x) (4 + -1x + (8x + -2x2)) = 10 + -1(2x * 2x) Combine like terms: -1x + 8x = 7x (4 + 7x + -2x2) = 10 + -1(2x * 2x) Reorder the terms for easier multiplication: 4 + 7x + -2x2 = 10 + -1(2 * 2x * x) Multiply 2 * 2 4 + 7x + -2x2 = 10 + -1(4x * x) Multiply x * x 4 + 7x + -2x2 = 10 + -1(4x2) Remove parenthesis around (4x2) 4 + 7x + -2x2 = 10 + -1 * 4x2 Multiply -1 * 4 4 + 7x + -2x2 = 10 + -4x2 Solving 4 + 7x + -2x2 = 10 + -4x2 Solving for variable 'x'. Reorder the terms: 4 + -10 + 7x + -2x2 + 4x2 = 10 + -4x2 + -10 + 4x2 Combine like terms: 4 + -10 = -6 -6 + 7x + -2x2 + 4x2 = 10 + -4x2 + -10 + 4x2 Combine like terms: -2x2 + 4x2 = 2x2 -6 + 7x + 2x2 = 10 + -4x2 + -10 + 4x2 Reorder the terms: -6 + 7x + 2x2 = 10 + -10 + -4x2 + 4x2 Combine like terms: 10 + -10 = 0 -6 + 7x + 2x2 = 0 + -4x2 + 4x2 -6 + 7x + 2x2 = -4x2 + 4x2 Combine like terms: -4x2 + 4x2 = 0 -6 + 7x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -3 + 3.5x + x2 = 0 Move the constant term to the right: Add '3' to each side of the equation. -3 + 3.5x + 3 + x2 = 0 + 3 Reorder the terms: -3 + 3 + 3.5x + x2 = 0 + 3 Combine like terms: -3 + 3 = 0 0 + 3.5x + x2 = 0 + 3 3.5x + x2 = 0 + 3 Combine like terms: 0 + 3 = 3 3.5x + x2 = 3 The x term is 3.5x. Take half its coefficient (1.75). Square it (3.0625) and add it to both sides. Add '3.0625' to each side of the equation. 3.5x + 3.0625 + x2 = 3 + 3.0625 Reorder the terms: 3.0625 + 3.5x + x2 = 3 + 3.0625 Combine like terms: 3 + 3.0625 = 6.0625 3.0625 + 3.5x + x2 = 6.0625 Factor a perfect square on the left side: (x + 1.75)(x + 1.75) = 6.0625 Calculate the square root of the right side: 2.46221445 Break this problem into two subproblems by setting (x + 1.75) equal to 2.46221445 and -2.46221445.Subproblem 1
x + 1.75 = 2.46221445 Simplifying x + 1.75 = 2.46221445 Reorder the terms: 1.75 + x = 2.46221445 Solving 1.75 + x = 2.46221445 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.75' to each side of the equation. 1.75 + -1.75 + x = 2.46221445 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + x = 2.46221445 + -1.75 x = 2.46221445 + -1.75 Combine like terms: 2.46221445 + -1.75 = 0.71221445 x = 0.71221445 Simplifying x = 0.71221445Subproblem 2
x + 1.75 = -2.46221445 Simplifying x + 1.75 = -2.46221445 Reorder the terms: 1.75 + x = -2.46221445 Solving 1.75 + x = -2.46221445 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.75' to each side of the equation. 1.75 + -1.75 + x = -2.46221445 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + x = -2.46221445 + -1.75 x = -2.46221445 + -1.75 Combine like terms: -2.46221445 + -1.75 = -4.21221445 x = -4.21221445 Simplifying x = -4.21221445Solution
