## candice1 3 years ago simlify the sum. (2u^3+2u^2+7)+(5u^3-2u+8) i need help this math problem is hard.

1. ParthKohli

Where do you have the problem?

2. candice1

????

3. ParthKohli

Do you know what like terms are?

4. candice1

no i have been out of school for 2 years for health issues and i came back and they just threw this at me like i knew how to do it.?

5. ParthKohli

Okay, like terms are for example: -> 5y^2 and -2y^2 -> 3x and 4x -> 5 and 2 -> 3x^3 and 6x^2 They have the numerical coefficients different, but they have the rest of the expression same. They can be added or subtracted.

6. candice1

okay so watt are you saying? (just curious)

7. ParthKohli

You have gotta add the like terms together :)

8. ParthKohli

Answer would be \[\Large 7u^{3} + 2u^{2} - 2u + 15 \]
