Simplify each expression
a. 5n2 − 3n2
b. 8 + 3b − 2c − 4 + 6b
(these are the answer choices)
a. a. −2n2
b. 9b − 2c + 4
b. a. −8n2
b. 9b − 2c + 4
c. a. 2n2
b. 9b − 2c + 4
d. a. 8n2
b. 9b − 2c + 4

Alright now combine all like terms remember no matter what you can allways add like terms ok now it would be 5-3 you should get two now add the n and the squared 2 and 2n2 should be your answer witch is A Now for the other equation 8+-4 =4 3b +6b = 9b now drag the 2c down and you get 4+9b-2c I hope this helps you
