Answer:

If solving an equation, put it in standard form with 0 on one side and simplify. [ details ]

Know how many roots to expect. [ details ]

If you’re down to a linear or quadratic equation (degree 1 or 2), solve by inspection or the quadratic formula. [ details ]

Then go to step 7.

Find one rational factor or root. This is the hard part, but there are lots of techniques to help you. [ details ]

If you can find a factor or root, continue with step 5 below; if you can’t, go to step 6.

Divide by your factor. This leaves you with a new reduced polynomial whose degree is 1 less. [ details ]

For the rest of the problem, you’ll work with the reduced polynomial and not the original. Continue at step 3.

If you can’t find a factor or root, turn to numerical methods. [ details ]

Then go to step 7.

If this was an equation to solve, write down the roots. If it was a polynomial to factor, write it in factored form, including any constant factors you took out in step
