Simplifying x2 + 13x + -30 = 100 Reorder the terms: -30 + 13x + x2 = 100 Solving -30 + 13x + x2 = 100 Solving for variable 'x'. Reorder the terms: -30 + -100 + 13x + x2 = 100 + -100 Combine like terms: -30 + -100 = -130 -130 + 13x + x2 = 100 + -100 Combine like terms: 100 + -100 = 0 -130 + 13x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '130' to each side of the equation. -130 + 13x + 130 + x2 = 0 + 130 Reorder the terms: -130 + 130 + 13x + x2 = 0 + 130 Combine like terms: -130 + 130 = 0 0 + 13x + x2 = 0 + 130 13x + x2 = 0 + 130 Combine like terms: 0 + 130 = 130 13x + x2 = 130 The x term is 13x. Take half its coefficient (6.5). Square it (42.25) and add it to both sides. Add '42.25' to each side of the equation. 13x + 42.25 + x2 = 130 + 42.25 Reorder the terms: 42.25 + 13x + x2 = 130 + 42.25 Combine like terms: 130 + 42.25 = 172.25 42.25 + 13x + x2 = 172.25 Factor a perfect square on the left side: (x + 6.5)(x + 6.5) = 172.25 Calculate the square root of the right side: 13.124404748 Break this problem into two subproblems by setting (x + 6.5) equal to 13.124404748 and -13.124404748.Subproblem 1
x + 6.5 = 13.124404748 Simplifying x + 6.5 = 13.124404748 Reorder the terms: 6.5 + x = 13.124404748 Solving 6.5 + x = 13.124404748 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6.5' to each side of the equation. 6.5 + -6.5 + x = 13.124404748 + -6.5 Combine like terms: 6.5 + -6.5 = 0.0 0.0 + x = 13.124404748 + -6.5 x = 13.124404748 + -6.5 Combine like terms: 13.124404748 + -6.5 = 6.624404748 x = 6.624404748 Simplifying x = 6.624404748Subproblem 2
x + 6.5 = -13.124404748 Simplifying x + 6.5 = -13.124404748 Reorder the terms: 6.5 + x = -13.124404748 Solving 6.5 + x = -13.124404748 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6.5' to each side of the equation. 6.5 + -6.5 + x = -13.124404748 + -6.5 Combine like terms: 6.5 + -6.5 = 0.0 0.0 + x = -13.124404748 + -6.5 x = -13.124404748 + -6.5 Combine like terms: -13.124404748 + -6.5 = -19.624404748 x = -19.624404748 Simplifying x = -19.624404748Solution
The solution to the problem is based on the solutions from the subproblems. x = {6.624404748, -19.624404748}
