    yes right so factor menas take out common stuff right so first question when you take out y^2 from first term how many y will left in the parentheses \[\huge\rm 3x^2y^2 − 2xy^2 − 8y^2\]

    or in other words divide all 3 terms by common factor

    \[ \huge\rm \frac{ 3x^2y^2 }{ y^2 }-\frac{ 2xy^2 }{ y^2}-\frac{ 8y^2 }{ y^2 }\]

    So the y^2 would cancel out?

    so i would apply *Headphone* method find two number if you multiply them you should get product of AC and if you add or subtract them you should get middle term a=leading coefficient b=middle term c=constant term

    yep a =3 and c=-8 so multiply them ac =3 times -8 = -24 find two number if you multiply them you should get -24 and if you add or subtract them you should get -2

    so the answer is y^2(3x+4)(x-2)
