Question

What's 7y^2 - y^2? HELP!

Answer 1

7y^2 - y^2 = 6y^2 i think!

Answer 2

Hey there...
Let's solve this problem by steps.

Method 1 -
Step 1 --> Taking GCF
$y^2 ( 7 - 1 )$

Step 2 ---> Combining like terms
$y^2 ( 6)$

Or

$6y^2$  is your final answer.

Method 2 -
We can straight way subtract $y^2$ from $7y^2$ which is
$7y^2 - y^2$
$=\ \textgreater \ 6y^2$ 

Hope it helped you..  :)
