Simplifying 0 = x2 + -10x + -900 Reorder the terms: 0 = -900 + -10x + x2 Solving 0 = -900 + -10x + x2 Solving for variable 'x'. Combine like terms: 0 + 900 = 900 900 + 10x + -1x2 = -900 + -10x + x2 + 900 + 10x + -1x2 Reorder the terms: 900 + 10x + -1x2 = -900 + 900 + -10x + 10x + x2 + -1x2 Combine like terms: -900 + 900 = 0 900 + 10x + -1x2 = 0 + -10x + 10x + x2 + -1x2 900 + 10x + -1x2 = -10x + 10x + x2 + -1x2 Combine like terms: -10x + 10x = 0 900 + 10x + -1x2 = 0 + x2 + -1x2 900 + 10x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 900 + 10x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -900 + -10x + x2 = 0 Move the constant term to the right: Add '900' to each side of the equation. -900 + -10x + 900 + x2 = 0 + 900 Reorder the terms: -900 + 900 + -10x + x2 = 0 + 900 Combine like terms: -900 + 900 = 0 0 + -10x + x2 = 0 + 900 -10x + x2 = 0 + 900 Combine like terms: 0 + 900 = 900 -10x + x2 = 900 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 = 900 + 25 Reorder the terms: 25 + -10x + x2 = 900 + 25 Combine like terms: 900 + 25 = 925 25 + -10x + x2 = 925 Factor a perfect square on the left side: (x + -5)(x + -5) = 925 Calculate the square root of the right side: 30.413812651 Break this problem into two subproblems by setting (x + -5) equal to 30.413812651 and -30.413812651.Subproblem 1
x + -5 = 30.413812651 Simplifying x + -5 = 30.413812651 Reorder the terms: -5 + x = 30.413812651 Solving -5 + x = 30.413812651 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right.
