Simplifying 2x2 + 20x + -11 = 0 Reorder the terms: -11 + 20x + 2x2 = 0 Solving -11 + 20x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -5.5 + 10x + x2 = 0 Move the constant term to the right: Add '5.5' to each side of the equation. -5.5 + 10x + 5.5 + x2 = 0 + 5.5 Reorder the terms: -5.5 + 5.5 + 10x + x2 = 0 + 5.5 Combine like terms: -5.5 + 5.5 = 0.0 0.0 + 10x + x2 = 0 + 5.5 10x + x2 = 0 + 5.5 Combine like terms: 0 + 5.5 = 5.5 10x + x2 = 5.5 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 = 5.5 + 25 Reorder the terms: 25 + 10x + x2 = 5.5 + 25 Combine like terms: 5.5 + 25 = 30.5 25 + 10x + x2 = 30.5 Factor a perfect square on the left side: (x + 5)(x + 5) = 30.5 Calculate the square root of the right side: 5.522680509 Break this problem into two subproblems by setting (x + 5) equal to 5.522680509 and -5.522680509.Subproblem 1
x + 5 = 5.522680509 Simplifying x + 5 = 5.522680509 Reorder the terms: 5 + x = 5.522680509 Solving 5 + x = 5.522680509 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 = 5.522680509 + -5 Combine like terms: 5 + -5 = 0 0 + x = 5.522680509 + -5 x = 5.522680509 + -5 Combine like terms: 5.522680509 + -5 = 0.522680509 x = 0.522680509 Simplifying x = 0.522680509Subproblem 2
x + 5 = -5.522680509 Simplifying x + 5 = -5.522680509 Reorder the terms: 5 + x = -5.522680509 Solving 5 + x = -5.522680509 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 = -5.522680509 + -5 Combine like terms: 5 + -5 = 0 0 + x = -5.522680509 + -5 x = -5.522680509 + -5 Combine like terms: -5.522680509 + -5 = -10.522680509 x = -10.522680509 Simplifying x = -10.522680509Solution
