Hey!
Let's write the problem.
[tex]\left(10g^2+3g-10\right)+\left(2g^2+g+7\right)[/tex]
Remove the parenthesis.
[tex]=10g^2+3g-10+2g^2+g+7[/tex]
Add like terms...
[tex]3g+g=4g[/tex]
[tex]10g^2+2g^2=12g^2[/tex]
We would be left with something like this,
[tex]=12g^2+4g+7-10[/tex]
Subtract the numbers.
[tex]=12g^2+4g-3[/tex]
That would be our final answer!
Thanks!
