Simplifying -0.1x2 + 90x = 20250 Reorder the terms: 90x + -0.1x2 = 20250 Solving 90x + -0.1x2 = 20250 Solving for variable 'x'. Reorder the terms: -20250 + 90x + -0.1x2 = 20250 + -20250 Combine like terms: 20250 + -20250 = 0 -20250 + 90x + -0.1x2 = 0 Begin completing the square. Divide all terms by -0.1 the coefficient of the squared term: Divide each side by '-0.1'. 202500 + -900x + x2 = 0 Move the constant term to the right: Add '-202500' to each side of the equation. 202500 + -900x + -202500 + x2 = 0 + -202500 Reorder the terms: 202500 + -202500 + -900x + x2 = 0 + -202500 Combine like terms: 202500 + -202500 = 0 0 + -900x + x2 = 0 + -202500 -900x + x2 = 0 + -202500 Combine like terms: 0 + -202500 = -202500 -900x + x2 = -202500 The x term is -900x. Take half its coefficient (-450). Square it (202500) and add it to both sides. Add '202500' to each side of the equation. -900x + 202500 + x2 = -202500 + 202500 Reorder the terms: 202500 + -900x + x2 = -202500 + 202500 Combine like terms: -202500 + 202500 = 0 202500 + -900x + x2 = 0 Factor a perfect square on the left side: (x + -450)(x + -450) = 0 Calculate the square root of the right side: 0 Break this problem into two subproblems by setting (x + -450) equal to 0 and 0.Subproblem 1
x + -450 = 0 Simplifying x + -450 = 0 Reorder the terms: -450 + x = 0 Solving -450 + x = 0 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '450' to each side of the equation. -450 + 450 + x = 0 + 450 Combine like terms: -450 + 450 = 0 0 + x = 0 + 450 x = 0 + 450 Combine like terms: 0 + 450 = 450 x = 450 Simplifying x = 450Subproblem 2
x + -450 = 0 Simplifying x + -450 = 0 Reorder the terms: -450 + x = 0 Solving -450 + x = 0 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '450' to each side of the equation. -450 + 450 + x = 0 + 450 Combine like terms: -450 + 450 = 0 0 + x = 0 + 450 x = 0 + 450 Combine like terms: 0 + 450 = 450 x = 450 Simplifying x = 450Solution
The solution to the problem is based on the solutions from the subproblems. x = {450, 450}
