Simplifying 1x2 + 10x + -80 = 0 Reorder the terms: -80 + 10x + 1x2 = 0 Solving -80 + 10x + 1x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '80' to each side of the equation. -80 + 10x + 80 + x2 = 0 + 80 Reorder the terms: -80 + 80 + 10x + x2 = 0 + 80 Combine like terms: -80 + 80 = 0 0 + 10x + x2 = 0 + 80 10x + x2 = 0 + 80 Combine like terms: 0 + 80 = 80 10x + x2 = 80 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 = 80 + 25 Reorder the terms: 25 + 10x + x2 = 80 + 25 Combine like terms: 80 + 25 = 105 25 + 10x + x2 = 105 Factor a perfect square on the left side: (x + 5)(x + 5) = 105 Calculate the square root of the right side: 10.246950766 Break this problem into two subproblems by setting (x + 5) equal to 10.246950766 and -10.246950766.Subproblem 1
x + 5 = 10.246950766 Simplifying x + 5 = 10.246950766 Reorder the terms: 5 + x = 10.246950766 Solving 5 + x = 10.246950766 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right.
