3b^5(4b^2-5)

OpenStudy (jtvatsim):

what's the question asking you to do with this? simplify? solve?

OpenStudy (anonymous):

use the distributive property to remove parenthesis

OpenStudy (jtvatsim):

OK, do you know how to use the distributive property? or what it is? :)

OpenStudy (anonymous):

Yes but idk what to do with the 5

OpenStudy (jtvatsim):

Ah, I see. That is a bit tricky. Let's see what we can do. :)

OpenStudy (jtvatsim):

So, just to make sure we know the same thing, the distributive property states that you multiply the insides by the outside and sum the result.

OpenStudy (jtvatsim):

So, we have \[3b^5(4b^2 - 5) = 3b^5*4b^2 - 3b^5*5\]

OpenStudy (jtvatsim):

does that make sense? any confusion there? :)

OpenStudy (jtvatsim):

we still have a few steps left... :)

OpenStudy (jtvatsim):
