How would you rewrite the expression 18x^3y^4+12x^5y^2 by factoring out the GCF?

The greatest common factor (GCF) of 18x^3y^4 and 12x^5y^2 is 6x^3y^2. To factor out the GCF, divide each term by the GCF:

18x^3y^4 / 6x^3y^2 = 3y^2
12x^5y^2 / 6x^3y^2 = 2x^2

Therefore, the expression can be rewritten as:

6x^3y^2(3y^2 + 2x^2)
