Simplifying (1.7 + -1x)(0.8 + -1x) + -1.2 * 0.3 = 0 Multiply (1.7 + -1x) * (0.8 + -1x) (1.7(0.8 + -1x) + -1x * (0.8 + -1x)) + -1.2 * 0.3 = 0 ((0.8 * 1.7 + -1x * 1.7) + -1x * (0.8 + -1x)) + -1.2 * 0.3 = 0 ((1.36 + -1.7x) + -1x * (0.8 + -1x)) + -1.2 * 0.3 = 0 (1.36 + -1.7x + (0.8 * -1x + -1x * -1x)) + -1.2 * 0.3 = 0 (1.36 + -1.7x + (-0.8x + 1x2)) + -1.2 * 0.3 = 0 Combine like terms: -1.7x + -0.8x = -2.5x (1.36 + -2.5x + 1x2) + -1.2 * 0.3 = 0 Multiply -1.2 * 0.3 1.36 + -2.5x + 1x2 + -0.36 = 0 Reorder the terms: 1.36 + -0.36 + -2.5x + 1x2 = 0 Combine like terms: 1.36 + -0.36 = 1 1 + -2.5x + 1x2 = 0 Solving 1 + -2.5x + 1x2 = 0 Solving for variable 'x'. Begin completing the square. 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 = 0.5625 1.5625 + -2.5x + x2 = 0.5625 Factor a perfect square on the left side: (x + -1.25)(x + -1.25) = 0.5625 Calculate the square root of the right side: 0.75 Break this problem into two subproblems by setting (x + -1.25) equal to 0.75 and -0.75.Subproblem 1
x + -1.25 = 0.75 Simplifying x + -1.25 = 0.75 Reorder the terms: -1.25 + x = 0.75 Solving -1.25 + x = 0.75 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 = 0.75 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + x = 0.75 + 1.25 x = 0.75 + 1.25 Combine like terms: 0.75 + 1.25 = 2 x = 2 Simplifying x = 2Subproblem 2
x + -1.25 = -0.75 Simplifying x + -1.25 = -0.75 Reorder the terms: -1.25 + x = -0.75 Solving -1.25 + x = -0.75 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 = -0.75 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + x = -0.75 + 1.25 x = -0.75 + 1.25 Combine like terms: -0.75 + 1.25 = 0.5 x = 0.5 Simplifying x = 0.5Solution
The solution to the problem is based on the solutions from the subproblems. x = {2, 0.5}
