Thread: Linear factors of polynomial

Find the linear factors of

first look here:

Rational root theorem - Wikipedia, the free encyclopedia

now armed with this new knowledge we can see that x = -1 is a possible root of the polynomial, and after substituting it in the polynomial we see that it's indeed a root, now all we have to do is reduce the polynomial to second degree by long division

The rational root theorem tell us that if this has a linear factor with rational
coeficients it is one of: .

Working our way through these shows that is in fact a factor and:




and the quadratic you can deal with using the quadratic formula.
