Simplifying 0 = -1x2 + -5x + 10 Reorder the terms: 0 = 10 + -5x + -1x2 Solving 0 = 10 + -5x + -1x2 Solving for variable 'x'. Combine like terms: 0 + -10 = -10 -10 + 5x + x2 = 10 + -5x + -1x2 + -10 + 5x + x2 Reorder the terms: -10 + 5x + x2 = 10 + -10 + -5x + 5x + -1x2 + x2 Combine like terms: 10 + -10 = 0 -10 + 5x + x2 = 0 + -5x + 5x + -1x2 + x2 -10 + 5x + x2 = -5x + 5x + -1x2 + x2 Combine like terms: -5x + 5x = 0 -10 + 5x + x2 = 0 + -1x2 + x2 -10 + 5x + x2 = -1x2 + x2 Combine like terms: -1x2 + x2 = 0 -10 + 5x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '10' to each side of the equation. -10 + 5x + 10 + x2 = 0 + 10 Reorder the terms: -10 + 10 + 5x + x2 = 0 + 10 Combine like terms: -10 + 10 = 0 0 + 5x + x2 = 0 + 10 5x + x2 = 0 + 10 Combine like terms: 0 + 10 = 10 5x + x2 = 10 The x term is 5x. Take half its coefficient (2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. 5x + 6.25 + x2 = 10 + 6.25 Reorder the terms: 6.25 + 5x + x2 = 10 + 6.25 Combine like terms: 10 + 6.25 = 16.25 6.25 + 5x + x2 = 16.25 Factor a perfect square on the left side: (x + 2.5)(x + 2.5) = 16.25 Calculate the square root of the right side: 4.031128874 Break this problem into two subproblems by setting (x + 2.5) equal to 4.031128874 and -4.031128874.Subproblem 1
x + 2.5 = 4.031128874 Simplifying x + 2.5 = 4.031128874 Reorder the terms: 2.5 + x = 4.031128874 Solving 2.5 + x = 4.031128874 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.5' to each side of the equation. 2.5 + -2.5 + x = 4.031128874 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + x = 4.031128874 + -2.5 x = 4.031128874 + -2.5 Combine like terms: 4.031128874 + -2.5 = 1.531128874 x = 1.531128874 Simplifying x = 1.531128874Subproblem 2
x + 2.5 = -4.031128874 Simplifying x + 2.5 = -4.031128874 Reorder the terms: 2.5 + x = -4.031128874 Solving 2.5 + x = -4.031128874 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.5' to each side of the equation. 2.5 + -2.5 + x = -4.031128874 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + x = -4.031128874 + -2.5 x = -4.031128874 + -2.5 Combine like terms: -4.031128874 + -2.5 = -6.531128874 x = -6.531128874 Simplifying x = -6.531128874Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.531128874, -6.531128874}
