Hey!
It looks like you meant: [tex]20x^3y+30x^2y^2[/tex]
Then, we are going to change the expression, specially the exponents. The reason behind this is because we don't want anything to be cubed. Here's an example: [tex]\:a^{b+c}=a^ba^c[/tex]
[tex]=20x^2xy+30x^2yy[/tex]
Factor out the common term, which is [tex]10x^2y[/tex]
[tex]=10x^2y\left(2x+3y\right)[/tex]
Done!
Let me know if you have any questions regarding this problem!
Thanks!
