simpify (5c^2-2c+4) + (c^2+2c)

Sagot :

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) = 2(3c^2+2)
