Simplifying (x + 0.9)(x + 1.8) = 0 Reorder the terms: (0.9 + x)(x + 1.8) = 0 Reorder the terms: (0.9 + x)(1.8 + x) = 0 Multiply (0.9 + x) * (1.8 + x) (0.9(1.8 + x) + x(1.8 + x)) = 0 ((1.8 * 0.9 + x * 0.9) + x(1.8 + x)) = 0 ((1.62 + 0.9x) + x(1.8 + x)) = 0 (1.62 + 0.9x + (1.8 * x + x * x)) = 0 (1.62 + 0.9x + (1.8x + x2)) = 0 Combine like terms: 0.9x + 1.8x = 2.7x (1.62 + 2.7x + x2) = 0 Solving 1.62 + 2.7x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-1.62' to each side of the equation. 1.62 + 2.7x + -1.62 + x2 = 0 + -1.62 Reorder the terms: 1.62 + -1.62 + 2.7x + x2 = 0 + -1.62 Combine like terms: 1.62 + -1.62 = 0.00 0.00 + 2.7x + x2 = 0 + -1.62 2.7x + x2 = 0 + -1.62 Combine like terms: 0 + -1.62 = -1.62 2.7x + x2 = -1.62 The x term is 2.7x. Take half its coefficient (1.35). Square it (1.8225) and add it to both sides. Add '1.8225' to each side of the equation. 2.7x + 1.8225 + x2 = -1.62 + 1.8225 Reorder the terms: 1.8225 + 2.7x + x2 = -1.62 + 1.8225 Combine like terms: -1.62 + 1.8225 = 0.2025 1.8225 + 2.7x + x2 = 0.2025 Factor a perfect square on the left side: (x + 1.35)(x + 1.35) = 0.2025 Calculate the square root of the right side: 0.45 Break this problem into two subproblems by setting (x + 1.35) equal to 0.45 and -0.45.Subproblem 1
x + 1.35 = 0.45 Simplifying x + 1.35 = 0.45 Reorder the terms: 1.35 + x = 0.45 Solving 1.35 + x = 0.45 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.35' to each side of the equation. 1.35 + -1.35 + x = 0.45 + -1.35 Combine like terms: 1.35 + -1.35 = 0.00 0.00 + x = 0.45 + -1.35 x = 0.45 + -1.35 Combine like terms: 0.45 + -1.35 = -0.9 x = -0.9 Simplifying x = -0.9Subproblem 2
x + 1.35 = -0.45 Simplifying x + 1.35 = -0.45 Reorder the terms: 1.35 + x = -0.45 Solving 1.35 + x = -0.45 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.35' to each side of the equation. 1.35 + -1.35 + x = -0.45 + -1.35 Combine like terms: 1.35 + -1.35 = 0.00 0.00 + x = -0.45 + -1.35 x = -0.45 + -1.35 Combine like terms: -0.45 + -1.35 = -1.8 x = -1.8 Simplifying x = -1.8Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.9, -1.8}
