Simplifying x2 + 9x = 328 Reorder the terms: 9x + x2 = 328 Solving 9x + x2 = 328 Solving for variable 'x'. Reorder the terms: -328 + 9x + x2 = 328 + -328 Combine like terms: 328 + -328 = 0 -328 + 9x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '328' to each side of the equation. -328 + 9x + 328 + x2 = 0 + 328 Reorder the terms: -328 + 328 + 9x + x2 = 0 + 328 Combine like terms: -328 + 328 = 0 0 + 9x + x2 = 0 + 328 9x + x2 = 0 + 328 Combine like terms: 0 + 328 = 328 9x + x2 = 328 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 = 328 + 20.25 Reorder the terms: 20.25 + 9x + x2 = 328 + 20.25 Combine like terms: 328 + 20.25 = 348.25 20.25 + 9x + x2 = 348.25 Factor a perfect square on the left side: (x + 4.5)(x + 4.5) = 348.25 Calculate the square root of the right side: 18.661457607 Break this problem into two subproblems by setting (x + 4.5) equal to 18.661457607 and -18.661457607.Subproblem 1
x + 4.5 = 18.661457607 Simplifying x + 4.5 = 18.661457607 Reorder the terms: 4.5 + x = 18.661457607 Solving 4.5 + x = 18.661457607 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 = 18.661457607 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = 18.661457607 + -4.5 x = 18.661457607 + -4.5 Combine like terms: 18.661457607 + -4.5 = 14.161457607 x = 14.161457607 Simplifying x = 14.161457607Subproblem 2
x + 4.5 = -18.661457607 Simplifying x + 4.5 = -18.661457607 Reorder the terms: 4.5 + x = -18.661457607 Solving 4.5 + x = -18.661457607 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 = -18.661457607 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = -18.661457607 + -4.5 x = -18.661457607 + -4.5 Combine like terms: -18.661457607 + -4.5 = -23.161457607 x = -23.161457607 Simplifying x = -23.161457607Solution
