Simplifying (x + 0.3)(x + 2.2) = 0 Reorder the terms: (0.3 + x)(x + 2.2) = 0 Reorder the terms: (0.3 + x)(2.2 + x) = 0 Multiply (0.3 + x) * (2.2 + x) (0.3(2.2 + x) + x(2.2 + x)) = 0 ((2.2 * 0.3 + x * 0.3) + x(2.2 + x)) = 0 ((0.66 + 0.3x) + x(2.2 + x)) = 0 (0.66 + 0.3x + (2.2 * x + x * x)) = 0 (0.66 + 0.3x + (2.2x + x2)) = 0 Combine like terms: 0.3x + 2.2x = 2.5x (0.66 + 2.5x + x2) = 0 Solving 0.66 + 2.5x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-0.66' to each side of the equation. 0.66 + 2.5x + -0.66 + x2 = 0 + -0.66 Reorder the terms: 0.66 + -0.66 + 2.5x + x2 = 0 + -0.66 Combine like terms: 0.66 + -0.66 = 0.00 0.00 + 2.5x + x2 = 0 + -0.66 2.5x + x2 = 0 + -0.66 Combine like terms: 0 + -0.66 = -0.66 2.5x + x2 = -0.66 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 = -0.66 + 1.5625 Reorder the terms: 1.5625 + 2.5x + x2 = -0.66 + 1.5625 Combine like terms: -0.66 + 1.5625 = 0.9025 1.5625 + 2.5x + x2 = 0.9025 Factor a perfect square on the left side: (x + 1.25)(x + 1.25) = 0.9025 Calculate the square root of the right side: 0.95 Break this problem into two subproblems by setting (x + 1.25) equal to 0.95 and -0.95.Subproblem 1
x + 1.25 = 0.95 Simplifying x + 1.25 = 0.95 Reorder the terms: 1.25 + x = 0.95 Solving 1.25 + x = 0.95 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 = 0.95 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = 0.95 + -1.25 x = 0.95 + -1.25 Combine like terms: 0.95 + -1.25 = -0.3 x = -0.3 Simplifying x = -0.3Subproblem 2
x + 1.25 = -0.95 Simplifying x + 1.25 = -0.95 Reorder the terms: 1.25 + x = -0.95 Solving 1.25 + x = -0.95 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 = -0.95 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = -0.95 + -1.25 x = -0.95 + -1.25 Combine like terms: -0.95 + -1.25 = -2.2 x = -2.2 Simplifying x = -2.2Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.3, -2.2}
