Simplifying 100 = 18x + -0.5x2 Solving 100 = 18x + -0.5x2 Solving for variable 'x'. Reorder the terms: 100 + -18x + 0.5x2 = 18x + -18x + -0.5x2 + 0.5x2 Combine like terms: 18x + -18x = 0 100 + -18x + 0.5x2 = 0 + -0.5x2 + 0.5x2 100 + -18x + 0.5x2 = -0.5x2 + 0.5x2 Combine like terms: -0.5x2 + 0.5x2 = 0.0 100 + -18x + 0.5x2 = 0.0 Begin completing the square. Divide all terms by 0.5 the coefficient of the squared term: Divide each side by '0.5'. 200 + -36x + x2 = 0 Move the constant term to the right: Add '-200' to each side of the equation. 200 + -36x + -200 + x2 = 0 + -200 Reorder the terms: 200 + -200 + -36x + x2 = 0 + -200 Combine like terms: 200 + -200 = 0 0 + -36x + x2 = 0 + -200 -36x + x2 = 0 + -200 Combine like terms: 0 + -200 = -200 -36x + x2 = -200 The x term is -36x. Take half its coefficient (-18). Square it (324) and add it to both sides. Add '324' to each side of the equation. -36x + 324 + x2 = -200 + 324 Reorder the terms: 324 + -36x + x2 = -200 + 324 Combine like terms: -200 + 324 = 124 324 + -36x + x2 = 124 Factor a perfect square on the left side: (x + -18)(x + -18) = 124 Calculate the square root of the right side: 11.135528726 Break this problem into two subproblems by setting (x + -18) equal to 11.135528726 and -11.135528726.Subproblem 1
x + -18 = 11.135528726 Simplifying x + -18 = 11.135528726 Reorder the terms: -18 + x = 11.135528726 Solving -18 + x = 11.135528726 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '18' to each side of the equation. -18 + 18 + x = 11.135528726 + 18 Combine like terms: -18 + 18 = 0 0 + x = 11.135528726 + 18 x = 11.135528726 + 18 Combine like terms: 11.135528726 + 18 = 29.135528726 x = 29.135528726 Simplifying x = 29.135528726Subproblem 2
x + -18 = -11.135528726 Simplifying x + -18 = -11.135528726 Reorder the terms: -18 + x = -11.135528726 Solving -18 + x = -11.135528726 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '18' to each side of the equation. -18 + 18 + x = -11.135528726 + 18 Combine like terms: -18 + 18 = 0 0 + x = -11.135528726 + 18 x = -11.135528726 + 18 Combine like terms: -11.135528726 + 18 = 6.864471274 x = 6.864471274 Simplifying x = 6.864471274Solution
