Question

Factor completely 20x3y + 30x2y2.

Answer 1

Hey!

It looks like you meant:
`20x^3y+30x^2y^2`
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:
`\:a^(b+c)=a^ba^c`

`=20x^2xy+30x^2yy`
Factor out the common term, which is
`10x^2y`

`=10x^2y\left(2x+3y\right)`
Done!

Let me know if you have any questions regarding this problem!
Thanks!
