Finding zeros of a polynomial.

I need help! I am also new to this...

question:

find the zeros of f(X)=(4x^2-49) / (2x+7)

This isn't bad.

The numerator is the difference of two squares. $x^{2}-y^{2}=(x-y)(x+y)$

You have:
. $\text{x}$ ....... $\text{y}$
. ${\downarrow}$ ....... ${\downarrow}$
$\frac{(2x)^{2}-(7)^{2}}{2x+7}$

Continue? It'll simplify down to something very easy.
