Question

factor out the greatest common factor
24xyz^2 + 20x^2 yz – 4x^2 z^2

Answer 1

since 24,20, and 4 are all divisible by 4, 4 is a common factor:
4[ (6xyz^2) + (5x^2yz) - (x^2 z^2) ]
now work on the variables. Since all of them have at least one x and z, pull htose out:
4xz[ 6yz + 5xy - xz ]
that is as far as you can get

Hope this helped!

Answer 2

\[24xyz ^{2}+20x ^{2}yz-4x ^{2}z ^{2}=4xz(6yz+5xy-xz)\]

Answer 3

thanks so much! i didnt know if i should do it by 2 or 4, but seeing as I needed the gcf...4 makes sense hahaha. <3 thanks
