Simplifying -50 + 20x + -1x2 = 0 Solving -50 + 20x + -1x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 50 + -20x + x2 = 0 Move the constant term to the right: Add '-50' to each side of the equation. 50 + -20x + -50 + x2 = 0 + -50 Reorder the terms: 50 + -50 + -20x + x2 = 0 + -50 Combine like terms: 50 + -50 = 0 0 + -20x + x2 = 0 + -50 -20x + x2 = 0 + -50 Combine like terms: 0 + -50 = -50 -20x + x2 = -50 The x term is -20x. Take half its coefficient (-10). Square it (100) and add it to both sides. Add '100' to each side of the equation. -20x + 100 + x2 = -50 + 100 Reorder the terms: 100 + -20x + x2 = -50 + 100 Combine like terms: -50 + 100 = 50 100 + -20x + x2 = 50 Factor a perfect square on the left side: (x + -10)(x + -10) = 50 Calculate the square root of the right side: 7.071067812 Break this problem into two subproblems by setting (x + -10) equal to 7.071067812 and -7.071067812.Subproblem 1
x + -10 = 7.071067812 Simplifying x + -10 = 7.071067812 Reorder the terms: -10 + x = 7.071067812 Solving -10 + x = 7.071067812 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '10' to each side of the equation. -10 + 10 + x = 7.071067812 + 10 Combine like terms: -10 + 10 = 0 0 + x = 7.071067812 + 10 x = 7.071067812 + 10 Combine like terms: 7.071067812 + 10 = 17.071067812 x = 17.071067812 Simplifying x = 17.071067812Subproblem 2
x + -10 = -7.071067812 Simplifying x + -10 = -7.071067812 Reorder the terms: -10 + x = -7.071067812 Solving -10 + x = -7.071067812 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '10' to each side of the equation. -10 + 10 + x = -7.071067812 + 10 Combine like terms: -10 + 10 = 0 0 + x = -7.071067812 + 10 x = -7.071067812 + 10 Combine like terms: -7.071067812 + 10 = 2.928932188 x = 2.928932188 Simplifying x = 2.928932188Solution
