Answer: 2(3c^2+2)
Step-by-step explanation:
Get rid of the parentheses : 5c^2-2c+4 + c^2+2c
Combine any like terms: 5c^2-2c+4 + c^2+2c = 6c^2-2c+4 +2c
Combine like terms: 6c^2-2c+4 +2c = 6c^2+4
Then just factor by grouping: (5c^2-2c+4) + (c^2+2c) = <u>2(3c^2+2)</u>

Hello,
Let's assume
2n-3 the first number
2n-1 the second
2n+1 the third
2n+3 the forth
2n-3+2n+3=3*(2n-3)-27
4n=6n-9-27
2n=36
==>2n-3=33
2n-1=35
2n+1=37
2n+3=39
Proof: 33+39=72
3*33-27=72
Is there anything else on the paper that can help me with that? like any questions at the top?
