Answer: w²+5w-6

Here is what we will have to multiply in this. We first need to multiply w from the first equation by both components of the second. It will look like this

w ×w=w ²
W ×6=6w

Now we have to do the same thing with the -1 from the first equation.

-1 ×w=-1w/-w
-1 ×6=-6

Now let’s put all of these numbers into an equation

w²+6w-w-6

This can be simplified by combining like terms. Let’s do this now.

w²+6w-w-6

w²+5w-6

Hope this is right and it helps :)
