Simplifying 150 = x2 + -13x Reorder the terms: 150 = -13x + x2 Solving 150 = -13x + x2 Solving for variable 'x'. Reorder the terms: 150 + 13x + -1x2 = -13x + 13x + x2 + -1x2 Combine like terms: -13x + 13x = 0 150 + 13x + -1x2 = 0 + x2 + -1x2 150 + 13x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 150 + 13x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -150 + -13x + x2 = 0 Move the constant term to the right: Add '150' to each side of the equation. -150 + -13x + 150 + x2 = 0 + 150 Reorder the terms: -150 + 150 + -13x + x2 = 0 + 150 Combine like terms: -150 + 150 = 0 0 + -13x + x2 = 0 + 150 -13x + x2 = 0 + 150 Combine like terms: 0 + 150 = 150 -13x + x2 = 150 The x term is -13x. Take half its coefficient (-6.5). Square it (42.25) and add it to both sides. Add '42.25' to each side of the equation. -13x + 42.25 + x2 = 150 + 42.25 Reorder the terms: 42.25 + -13x + x2 = 150 + 42.25 Combine like terms: 150 + 42.25 = 192.25 42.25 + -13x + x2 = 192.25 Factor a perfect square on the left side: (x + -6.5)(x + -6.5) = 192.25 Calculate the square root of the right side: 13.865424624 Break this problem into two subproblems by setting (x + -6.5) equal to 13.865424624 and -13.865424624.Subproblem 1
x + -6.5 = 13.865424624 Simplifying x + -6.5 = 13.865424624 Reorder the terms: -6.5 + x = 13.865424624 Solving -6.5 + x = 13.865424624 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '6.5' to each side of the equation. -6.5 + 6.5 + x = 13.865424624 + 6.5 Combine like terms: -6.5 + 6.5 = 0.0 0.0 + x = 13.865424624 + 6.5 x = 13.865424624 + 6.5 Combine like terms: 13.865424624 + 6.5 = 20.365424624 x = 20.365424624 Simplifying x = 20.365424624Subproblem 2
x + -6.5 = -13.865424624 Simplifying x + -6.5 = -13.865424624 Reorder the terms: -6.5 + x = -13.865424624 Solving -6.5 + x = -13.865424624 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '6.5' to each side of the equation. -6.5 + 6.5 + x = -13.865424624 + 6.5 Combine like terms: -6.5 + 6.5 = 0.0 0.0 + x = -13.865424624 + 6.5 x = -13.865424624 + 6.5 Combine like terms: -13.865424624 + 6.5 = -7.365424624 x = -7.365424624 Simplifying x = -7.365424624Solution
The solution to the problem is based on the solutions from the subproblems. x = {20.365424624, -7.365424624}
