Simplifying 1320 = x(x + -3) Reorder the terms: 1320 = x(-3 + x) 1320 = (-3 * x + x * x) 1320 = (-3x + x2) Solving 1320 = -3x + x2 Solving for variable 'x'. Reorder the terms: 1320 + 3x + -1x2 = -3x + 3x + x2 + -1x2 Combine like terms: -3x + 3x = 0 1320 + 3x + -1x2 = 0 + x2 + -1x2 1320 + 3x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 1320 + 3x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -1320 + -3x + x2 = 0 Move the constant term to the right: Add '1320' to each side of the equation. -1320 + -3x + 1320 + x2 = 0 + 1320 Reorder the terms: -1320 + 1320 + -3x + x2 = 0 + 1320 Combine like terms: -1320 + 1320 = 0 0 + -3x + x2 = 0 + 1320 -3x + x2 = 0 + 1320 Combine like terms: 0 + 1320 = 1320 -3x + x2 = 1320 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 = 1320 + 2.25 Reorder the terms: 2.25 + -3x + x2 = 1320 + 2.25 Combine like terms: 1320 + 2.25 = 1322.25 2.25 + -3x + x2 = 1322.25 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 1322.25 Calculate the square root of the right side: 36.362755671 Break this problem into two subproblems by setting (x + -1.5) equal to 36.362755671 and -36.362755671.Subproblem 1
x + -1.5 = 36.362755671 Simplifying x + -1.5 = 36.362755671 Reorder the terms: -1.5 + x = 36.362755671 Solving -1.5 + x = 36.362755671 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 = 36.362755671 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = 36.362755671 + 1.5 x = 36.362755671 + 1.5 Combine like terms: 36.362755671 + 1.5 = 37.862755671 x = 37.862755671 Simplifying x = 37.862755671Subproblem 2
x + -1.5 = -36.362755671 Simplifying x + -1.5 = -36.362755671 Reorder the terms: -1.5 + x = -36.362755671 Solving -1.5 + x = -36.362755671 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 = -36.362755671 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = -36.362755671 + 1.5 x = -36.362755671 + 1.5 Combine like terms: -36.362755671 + 1.5 = -34.862755671 x = -34.862755671 Simplifying x = -34.862755671Solution
The solution to the problem is based on the solutions from the subproblems. x = {37.862755671, -34.862755671}
