Simplifying x2 + 10x + -42 = 0 Reorder the terms: -42 + 10x + x2 = 0 Solving -42 + 10x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '42' to each side of the equation. -42 + 10x + 42 + x2 = 0 + 42 Reorder the terms: -42 + 42 + 10x + x2 = 0 + 42 Combine like terms: -42 + 42 = 0 0 + 10x + x2 = 0 + 42 10x + x2 = 0 + 42 Combine like terms: 0 + 42 = 42 10x + x2 = 42 The x term is 10x. Take half its coefficient (5). Square it (25) and add it to both sides. Add '25' to each side of the equation. 10x + 25 + x2 = 42 + 25 Reorder the terms: 25 + 10x + x2 = 42 + 25 Combine like terms: 42 + 25 = 67 25 + 10x + x2 = 67 Factor a perfect square on the left side: (x + 5)(x + 5) = 67 Calculate the square root of the right side: 8.185352772 Break this problem into two subproblems by setting (x + 5) equal to 8.185352772 and -8.185352772.Subproblem 1
x + 5 = 8.185352772 Simplifying x + 5 = 8.185352772 Reorder the terms: 5 + x = 8.185352772 Solving 5 + x = 8.185352772 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + x = 8.185352772 + -5 Combine like terms: 5 + -5 = 0 0 + x = 8.185352772 + -5 x = 8.185352772 + -5 Combine like terms: 8.185352772 + -5 = 3.185352772 x = 3.185352772 Simplifying x = 3.185352772Subproblem 2
x + 5 = -8.185352772 Simplifying x + 5 = -8.185352772 Reorder the terms: 5 + x = -8.185352772 Solving 5 + x = -8.185352772 Solving for variable 'x'.
