Question

[4 - (3c - 1)][6 - ( 3c - 1)]

Answer 1

Hi there!

You would have to simplify the terms inside [ ] this thing, then multiply.

So let's simplify them first.

4 - (3c - 1) 
use distributive property.....
4 - 3c + 1
-3c + 5

6 - (3c - 1)
use distributive property again...
6 - 3c + 1
-3c + 7

so now, multiply (-3c + 5)(-3c + 7).
(-3c + 5)(-3c + 7)
9c² - 21c - 15c + 35
9c² - 36c + 35

So your final answer is...
9c² - 36c + 35

Hope this helped! :)

Answer 2

(4-3c+1)(6-3c+1)
= 24 -12c + 4 - 18c +9c^2 - 3c +6 -3c + 1
= 35 - 36c +9c^2

Here is the answer (I am not sure if you need to factor it or not so I will give you both versions):

35 - 36c +9c^2
or
(7 - 3c)(5-3c)

I hope this helps :)
