Question:the numbers after the coefficient is the exponent
It is just like multiplying the second set of parentheses by a negative one.
c3 + -c2+ 2c + 3c3 +3c2 + 4c
Then you combine your like terms.
(c3 + 3c3) + (3c2 + -c2) + (2c + 4c)
Add the parentheses.
4c3 + 2c2 +6c
Then factor a "2c" out of it...
2c(2c2 +c +3)
That is your final answer.
c^3 - c^2 + 2c + 3c^3 + 3c^2 + 4c
(because a minus outside the bracket changes the sign of every term inside the bracket, once you remove the brackets)
Group all the like terms together.
c^3 + 3c^3 - c^2 + 3c^2 + 4c + 2c
which is the same as
4c^3 + 2c^2 +6c
That simplifies to 4c^3+2c^2+6c
combine the cubed terms (c^3 and 3c^3), and squared terms (-c^2 and 3c^2) and the linear terms (2c and 4c) to get the answer: 4c^3+2c^2+6c
