Simplifying x(x + -3) = 100 Reorder the terms: x(-3 + x) = 100 (-3 * x + x * x) = 100 (-3x + x2) = 100 Solving -3x + x2 = 100 Solving for variable 'x'. Reorder the terms: -100 + -3x + x2 = 100 + -100 Combine like terms: 100 + -100 = 0 -100 + -3x + x2 = 0 Begin completing the square. 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 = 11.611874208 x = 11.611874208 Simplifying x = 11.611874208Subproblem 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 = -8.611874208 x = -8.611874208 Simplifying x = -8.611874208Solution
The solution to the problem is based on the solutions from the subproblems. x = {11.611874208, -8.611874208}
