# How do you multiply #(2x^2+8)div(x^4-16)/(x^2+x-6)#?

##### 1 Answer

#### Explanation:

Take into account the formula:

We can apply this formula one more for

We can also do something with

formula for quadratic function:

where

We can use the following method only when a=1. In this particular example b=1 and c=-6

in order to get solution we have to:

The only way how to get 6 is by multiplying 6*1 or 3*2 then we have to resolve signs from the second equation

There is no way we can arrange 6 and 1 to get 1. so the solution is 3 and 2 and it's:

Now we can rewrite:
