Simplifying -15x2 + -45x + 1500 = 0 Reorder the terms: 1500 + -45x + -15x2 = 0 Solving 1500 + -45x + -15x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '15'. 15(100 + -3x + -1x2) = 0 Ignore the factor 15.Subproblem 1
Set the factor '(100 + -3x + -1x2)' equal to zero and attempt to solve: Simplifying 100 + -3x + -1x2 = 0 Solving 100 + -3x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -100 + 3x + x2 = 0 Move the constant term to the right: Add '100' to each side of the equation. -100 + 3x + 100 + x2 = 0 + 100 Reorder the terms: -100 + 100 + 3x + x2 = 0 + 100 Combine like terms: -100 + 100 = 0 0 + 3x + x2 = 0 + 100 3x + x2 = 0 + 100 Combine like terms: 0 + 100 = 100 3x + x2 = 100 The x term is 3x. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3x + 2.25 + x2 = 100 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 100 + 2.25 Combine like terms: 100 + 2.25 = 102.25 2.25 + 3x + x2 = 102.25 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 102.25 Calculate the square root of the right side: 10.111874208 Break this problem into two subproblems by setting (x + 1.5) equal to 10.111874208 and -10.111874208.Subproblem 1
x + 1.5 = 10.111874208 Simplifying x + 1.5 = 10.111874208 Reorder the terms: 1.5 + x = 10.111874208 Solving 1.5 + x = 10.111874208 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = 10.111874208 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 10.111874208 + -1.5 x = 10.111874208 + -1.5 Combine like terms: 10.111874208 + -1.5 = 8.611874208 x = 8.611874208 Simplifying x = 8.611874208Subproblem 2
x + 1.5 = -10.111874208 Simplifying x + 1.5 = -10.111874208 Reorder the terms: 1.5 + x = -10.111874208 Solving 1.5 + x = -10.111874208 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = -10.111874208 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -10.111874208 + -1.5 x = -10.111874208 + -1.5 Combine like terms: -10.111874208 + -1.5 = -11.611874208 x = -11.611874208 Simplifying x = -11.611874208Solution
The solution to the problem is based on the solutions from the subproblems. x = {8.611874208, -11.611874208}Solution
x = {8.611874208, -11.611874208}
