Simplifying 10x2 + 9x + -160 = 0 Reorder the terms: -160 + 9x + 10x2 = 0 Solving -160 + 9x + 10x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. -16 + 0.9x + x2 = 0 Move the constant term to the right: Add '16' to each side of the equation. -16 + 0.9x + 16 + x2 = 0 + 16 Reorder the terms: -16 + 16 + 0.9x + x2 = 0 + 16 Combine like terms: -16 + 16 = 0 0 + 0.9x + x2 = 0 + 16 0.9x + x2 = 0 + 16 Combine like terms: 0 + 16 = 16 0.9x + x2 = 16 The x term is 0.9x. Take half its coefficient (0.45). Square it (0.2025) and add it to both sides. Add '0.2025' to each side of the equation. 0.9x + 0.2025 + x2 = 16 + 0.2025 Reorder the terms: 0.2025 + 0.9x + x2 = 16 + 0.2025 Combine like terms: 16 + 0.2025 = 16.2025 0.2025 + 0.9x + x2 = 16.2025 Factor a perfect square on the left side: (x + 0.45)(x + 0.45) = 16.2025 Calculate the square root of the right side: 4.025232913 Break this problem into two subproblems by setting (x + 0.45) equal to 4.025232913 and -4.025232913.Subproblem 1
x + 0.45 = 4.025232913 Simplifying x + 0.45 = 4.025232913 Reorder the terms: 0.45 + x = 4.025232913 Solving 0.45 + x = 4.025232913 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.45' to each side of the equation. 0.45 + -0.45 + x = 4.025232913 + -0.45 Combine like terms: 0.45 + -0.45 = 0.00 0.00 + x = 4.025232913 + -0.45 x = 4.025232913 + -0.45 Combine like terms: 4.025232913 + -0.45 = 3.575232913 x = 3.575232913 Simplifying x = 3.575232913Subproblem 2
x + 0.45 = -4.025232913 Simplifying x + 0.45 = -4.025232913 Reorder the terms: 0.45 + x = -4.025232913 Solving 0.45 + x = -4.025232913 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.45' to each side of the equation. 0.45 + -0.45 + x = -4.025232913 + -0.45 Combine like terms: 0.45 + -0.45 = 0.00 0.00 + x = -4.025232913 + -0.45 x = -4.025232913 + -0.45 Combine like terms: -4.025232913 + -0.45 = -4.475232913 x = -4.475232913 Simplifying x = -4.475232913Solution
