Simplifying 0 = x2 + -12x + -300 Reorder the terms: 0 = -300 + -12x + x2 Solving 0 = -300 + -12x + x2 Solving for variable 'x'. Combine like terms: 0 + 300 = 300 300 + 12x + -1x2 = -300 + -12x + x2 + 300 + 12x + -1x2 Reorder the terms: 300 + 12x + -1x2 = -300 + 300 + -12x + 12x + x2 + -1x2 Combine like terms: -300 + 300 = 0 300 + 12x + -1x2 = 0 + -12x + 12x + x2 + -1x2 300 + 12x + -1x2 = -12x + 12x + x2 + -1x2 Combine like terms: -12x + 12x = 0 300 + 12x + -1x2 = 0 + x2 + -1x2 300 + 12x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 300 + 12x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -300 + -12x + x2 = 0 Move the constant term to the right: Add '300' to each side of the equation. -300 + -12x + 300 + x2 = 0 + 300 Reorder the terms: -300 + 300 + -12x + x2 = 0 + 300 Combine like terms: -300 + 300 = 0 0 + -12x + x2 = 0 + 300 -12x + x2 = 0 + 300 Combine like terms: 0 + 300 = 300 -12x + x2 = 300 The x term is -12x. Take half its coefficient (-6). Square it (36) and add it to both sides. Add '36' to each side of the equation. -12x + 36 + x2 = 300 + 36 Reorder the terms: 36 + -12x + x2 = 300 + 36 Combine like terms: 300 + 36 = 336 36 + -12x + x2 = 336 Factor a perfect square on the left side: (x + -6)(x + -6) = 336 Calculate the square root of the right side: 18.33030278 Break this problem into two subproblems by setting (x + -6) equal to 18.33030278 and -18.33030278.Subproblem 1
x + -6 = 18.33030278 Simplifying x + -6 = 18.33030278 Reorder the terms: -6 + x = 18.33030278 Solving -6 + x = 18.33030278 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '6' to each side of the equation. -6 + 6 + x = 18.33030278 + 6 Combine like terms: -6 + 6 = 0 0 + x = 18.33030278 + 6 x = 18.33030278 + 6 Combine like terms: 18.33030278 + 6 = 24.33030278 x = 24.33030278 Simplifying x = 24.33030278Subproblem 2
x + -6 = -18.33030278 Simplifying x + -6 = -18.33030278 Reorder the terms: -6 + x = -18.33030278 Solving -6 + x = -18.33030278 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '6' to each side of the equation. -6 + 6 + x = -18.33030278 + 6 Combine like terms: -6 + 6 = 0 0 + x = -18.33030278 + 6 x = -18.33030278 + 6 Combine like terms: -18.33030278 + 6 = -12.33030278 x = -12.33030278 Simplifying x = -12.33030278Solution
The solution to the problem is based on the solutions from the subproblems. x = {24.33030278, -12.33030278}
