use the distributive property to remove the parenthesis. simplify as much as possible.

3w^3(7-6w^5)

3w^3 * 7 = 21w^3

3w^3 * (-6w^5) = -18w^8

21w^3-18w^8

Is this right?

Which did you pick?

anonymous · Answer

We multiply:

3w^3 * 7

Which is just multiplying 7 and 3 and keeping w^3 the same.

Then we multiply:

3w^3 * -6w^5

We multiply -6 and 3 together, and then we add the exponents 3 + 5.

So we have:

$3 \times -6 \times w^{3 + 5}$

Can you do that? @Cassandra_Lea_96

anonymous · Answer

oh yeah it wasn't multiple choice or anything that's what I did I just wanted to make sure I did it right =) I broke it up and multiplied each group like you said and then I put them together and the answer I got was 21w^3-18w^8 =)

You got it! :D

anonymous · Answer

YES! lol =D thank you and really quick  the next one says to multiply and simplify and the equation is ; (y-1)(y+3)  is that FOIL? =o

anonymous · Answer

Yes, it is.

We multiply:

y * y

y * 3

-1 * y

-1 * 3

ok cool I can do it =) I just wanted to make sure it was Foil because it didn't say it on the problem =o
