Question

What is y squared plus 2 y plus 3 y squared

Answer 1

4y^2+2y

Answer 2

\[3y^2+y^2=4y^2\]
then add 2y making it
\[4y^2+2y\]

Answer 3

to make it a little bit better explanation, you are adding like terms. any time you have exponentials, you look at the ones that are similar and add the like terms together

Answer 4

I have y^2+2y+3y^2
1^2+2y+3y2
+2y+9y
1+11y=12y

Answer 5

\[y^2\] doesn't change to \[1^2\]

Answer 6

it is \[1y^2\]

Answer 7

so would the answer be 12y

Answer 8

no. combine like terms. the like terms are the \[y^2\] terms and the y terms.

for example, you have an equation\[4y^3+2y+y^3+15\]
the answer for this equation would be:\[5y^3+2y+15\] because the only like term is the cube

Answer 9

ok thank you for your help, im just not good with math

Answer 10

i am to an extent and that was a good one for me. I enjoy math, but only up to Algebra. I'm in Precalculus right now and it's kicking my butt. However, you are very welcome. Did you understand it though?

Answer 11

yes, my friend had explained it to me then i realized it was the same thing that you had told me
