Simplifying (x + 0.8)(x + 1.4) = 0 Reorder the terms: (0.8 + x)(x + 1.4) = 0 Reorder the terms: (0.8 + x)(1.4 + x) = 0 Multiply (0.8 + x) * (1.4 + x) (0.8(1.4 + x) + x(1.4 + x)) = 0 ((1.4 * 0.8 + x * 0.8) + x(1.4 + x)) = 0 ((1.12 + 0.8x) + x(1.4 + x)) = 0 (1.12 + 0.8x + (1.4 * x + x * x)) = 0 (1.12 + 0.8x + (1.4x + x2)) = 0 Combine like terms: 0.8x + 1.4x = 2.2x (1.12 + 2.2x + x2) = 0 Solving 1.12 + 2.2x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-1.12' to each side of the equation. 1.12 + 2.2x + -1.12 + x2 = 0 + -1.12 Reorder the terms: 1.12 + -1.12 + 2.2x + x2 = 0 + -1.12 Combine like terms: 1.12 + -1.12 = 0.00 0.00 + 2.2x + x2 = 0 + -1.12 2.2x + x2 = 0 + -1.12 Combine like terms: 0 + -1.12 = -1.12 2.2x + x2 = -1.12 The x term is 2.2x. Take half its coefficient (1.1). Square it (1.21) and add it to both sides. Add '1.21' to each side of the equation. 2.2x + 1.21 + x2 = -1.12 + 1.21 Reorder the terms: 1.21 + 2.2x + x2 = -1.12 + 1.21 Combine like terms: -1.12 + 1.21 = 0.09 1.21 + 2.2x + x2 = 0.09 Factor a perfect square on the left side: (x + 1.1)(x + 1.1) = 0.09 Calculate the square root of the right side: 0.3 Break this problem into two subproblems by setting (x + 1.1) equal to 0.3 and -0.3.Subproblem 1
x + 1.1 = 0.3 Simplifying x + 1.1 = 0.3 Reorder the terms: 1.1 + x = 0.3 Solving 1.1 + x = 0.3 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.1' to each side of the equation. 1.1 + -1.1 + x = 0.3 + -1.1 Combine like terms: 1.1 + -1.1 = 0.0 0.0 + x = 0.3 + -1.1 x = 0.3 + -1.1 Combine like terms: 0.3 + -1.1 = -0.8 x = -0.8 Simplifying x = -0.8Subproblem 2
x + 1.1 = -0.3 Simplifying x + 1.1 = -0.3 Reorder the terms: 1.1 + x = -0.3 Solving 1.1 + x = -0.3 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.1' to each side of the equation. 1.1 + -1.1 + x = -0.3 + -1.1 Combine like terms: 1.1 + -1.1 = 0.0 0.0 + x = -0.3 + -1.1 x = -0.3 + -1.1 Combine like terms: -0.3 + -1.1 = -1.4 x = -1.4 Simplifying x = -1.4Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.8, -1.4}
