What are the zeros of the function? What are the multiplicities?
$$(fx)=5x^3-5x^2-30x$$
Factor:
$$(5x)(x^2 - x - 6)$$
What do I do from there?

Question

What are the zeros of the function? What are the multiplicities? 
$$(fx)=5x^3-5x^2-30x$$
Factor:
$$(5x)(x^2 - x - 6)$$
What do I do from there?

hartnn · Answer

to get the zeros, equate f(x) = 0 

5x (x^2-x-6) = 0 

5x = 0 or x^2 -x-6 =0
can you solve that quadratic ?

$$x\; =\; \frac {-b\; \pm\; \sqrt {b^2\; -\; 4ac}}{2a}\$$
How would I in put that into the formula?

hartnn · Answer

you only know quadratic formula method ? 
do u also know factor method to solve quadratics ?

anonymous · Answer

Nope :/

hartnn · Answer

ok, lets do it by quadratic formula :)
