Simplifying x2 + -3x = 18 * 13 Reorder the terms: -3x + x2 = 18 * 13 Multiply 18 * 13 -3x + x2 = 234 Solving -3x + x2 = 234 Solving for variable 'x'. Reorder the terms: -234 + -3x + x2 = 234 + -234 Combine like terms: 234 + -234 = 0 -234 + -3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '234' to each side of the equation. -234 + -3x + 234 + x2 = 0 + 234 Reorder the terms: -234 + 234 + -3x + x2 = 0 + 234 Combine like terms: -234 + 234 = 0 0 + -3x + x2 = 0 + 234 -3x + x2 = 0 + 234 Combine like terms: 0 + 234 = 234 -3x + x2 = 234 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 = 234 + 2.25 Reorder the terms: 2.25 + -3x + x2 = 234 + 2.25 Combine like terms: 234 + 2.25 = 236.25 2.25 + -3x + x2 = 236.25 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 236.25 Calculate the square root of the right side: 15.370426149 Break this problem into two subproblems by setting (x + -1.5) equal to 15.370426149 and -15.370426149.Subproblem 1
x + -1.5 = 15.370426149 Simplifying x + -1.5 = 15.370426149 Reorder the terms: -1.5 + x = 15.370426149 Solving -1.5 + x = 15.370426149 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 = 15.370426149 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = 15.370426149 + 1.5 x = 15.370426149 + 1.5 Combine like terms: 15.370426149 + 1.5 = 16.870426149 x = 16.870426149 Simplifying x = 16.870426149Subproblem 2
x + -1.5 = -15.370426149 Simplifying x + -1.5 = -15.370426149 Reorder the terms: -1.5 + x = -15.370426149 Solving -1.5 + x = -15.370426149 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 = -15.370426149 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = -15.370426149 + 1.5 x = -15.370426149 + 1.5 Combine like terms: -15.370426149 + 1.5 = -13.870426149 x = -13.870426149 Simplifying x = -13.870426149Solution
The solution to the problem is based on the solutions from the subproblems. x = {16.870426149, -13.870426149}
