Please perform the indicated operations and simplify
(3x5)^2(2x+1)(x4)

(3x5)^2(2x+1)(x4)
use FOIL to expand each one
= 9x^2  30x + 25  (2x^2  8x + x  4)
now simplify 
Yes but doesn't 8x and x combine to become 7x? so then it should look like this?
2x^2 7x 4? 
of course ...
that is what I meant by simplify.
I was expecting you to finish the question.
can you tell me what the next few lines would be ? 
9x230x+25
2x2 7x 4

7x2 23+29
Is this correct? 
Thanks Breanna! Looks correct to me!

Perform the indicated operations and simplify (2x  6) (x + 1)  (x  7)^2
