WebFeb 10, 2024 · While quadratic equations have two solutions, cubics have three. You already have two of these — they're the answers you found for the "quadratic" portion of the problem in parentheses. In cases where your equation is eligible for this "factoring" method of solving, your third answer will always be . Factoring your equation into the form WebTake the solution (s) and put them in the original equation to see if they really work. Example: solve for x: 2x x − 3 + 3 = 6 x − 3 (x≠3) We have said x≠3 to avoid a division by zero. Let's multiply through by (x − 3): 2x + 3 (x−3) = 6 Bring the 6 to the left: 2x + 3 (x−3) − 6 = 0 Expand and solve: 2x + 3x − 9 − 6 = 0 5x − 15 = 0 5 (x − 3) = 0
