how do you simplifly 5y^2 - 2y - 3y^2 + y^2 - 1+ 6v^2

Question

The problem is 5y by the second power minus 2y minus 3y by the second power plus y by the second power minus 1 plus 6v by the second power 

Answer 1

Combine like terms: 5y^2 , -3y^2 and y^2 to get 

 

3y^2 -2y +6v^2-1

Answer 2

5y² - 2y - 3y² + y² - 1+ 6v²

 

What we do is combine like terms:

5y² - 3y² + y² = 3y²

-2y = -2y

-1 = -1

6v² = 6v²

 

so we have:

6v² + 3y² - 2y - 1

Answer 3

You will need to combine like terms.

 

5y² - 2y - 3y² + y² - 1 + 6v²

 

Re-arrange like so:

 

5y² - 3y² + y² + 6v² - 2y -1

 

Combine like terms:

 

3y² + 6v² - 2y - 1

Answer 4

Ashley, I make typos a lot!  If you meant 'v' then Heather S. gave a great answer; if you meant 'y' then read on:

 

5y^2 - 2y - 3y^2 + y^2 - 1+ 6y^2                    [the problem -- with a y instead of a v]

5y^2 + 3y^2 + y^2 + 6y^2 -2y -1                 [rearranged -- variables first (y^2, then y), then constants]

(5 + 3 +1 + 6)y^2 -2y - 1                       [use the distributive property; notice the assumed '1']

15y^2 - 2y -1
