Simplifying x(x + -9) = 30 Reorder the terms: x(-9 + x) = 30 (-9 * x + x * x) = 30 (-9x + x2) = 30 Solving -9x + x2 = 30 Solving for variable 'x'. Reorder the terms: -30 + -9x + x2 = 30 + -30 Combine like terms: 30 + -30 = 0 -30 + -9x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '30' to each side of the equation. -30 + -9x + 30 + x2 = 0 + 30 Reorder the terms: -30 + 30 + -9x + x2 = 0 + 30 Combine like terms: -30 + 30 = 0 0 + -9x + x2 = 0 + 30 -9x + x2 = 0 + 30 Combine like terms: 0 + 30 = 30 -9x + x2 = 30 The x term is -9x. Take half its coefficient (-4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. -9x + 20.25 + x2 = 30 + 20.25 Reorder the terms: 20.25 + -9x + x2 = 30 + 20.25 Combine like terms: 30 + 20.25 = 50.25 20.25 + -9x + x2 = 50.25 Factor a perfect square on the left side: (x + -4.5)(x + -4.5) = 50.25 Calculate the square root of the right side: 7.088723439 Break this problem into two subproblems by setting (x + -4.5) equal to 7.088723439 and -7.088723439.Subproblem 1
x + -4.5 = 7.088723439 Simplifying x + -4.5 = 7.088723439 Reorder the terms: -4.5 + x = 7.088723439 Solving -4.5 + x = 7.088723439 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4.5' to each side of the equation. -4.5 + 4.5 + x = 7.088723439 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + x = 7.088723439 + 4.5 x = 7.088723439 + 4.5 Combine like terms: 7.088723439 + 4.5 = 11.588723439 x = 11.588723439 Simplifying x = 11.588723439Subproblem 2
x + -4.5 = -7.088723439 Simplifying x + -4.5 = -7.088723439 Reorder the terms: -4.5 + x = -7.088723439 Solving -4.5 + x = -7.088723439 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4.5' to each side of the equation. -4.5 + 4.5 + x = -7.088723439 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + x = -7.088723439 + 4.5 x = -7.088723439 + 4.5 Combine like terms: -7.088723439 + 4.5 = -2.588723439 x = -2.588723439 Simplifying x = -2.588723439Solution
The solution to the problem is based on the solutions from the subproblems. x = {11.588723439, -2.588723439}
