In between the roots the function is either entirely above, or entirely below, the x-axis. Solve each binomial. Well, let us put "3" in place of x: Flag as... You know this because the equation is equal to 0 and any number times 0 is equal to 0.

If we find one root, we can then reduce the polynomial by one degree example later and this may be enough to solve the whole polynomial. A "root" is when y is zero: To do this, factor out a term common to the second two terms in the polynomial. This article has also been viewed 150,761 times.
