Question

is this the correct answer?
2a^4m-32b^8m
2(a^4m-16b^8m)

Answer 1

factor out the m as well. then you can go further because you have the difference of two squares

Answer 2

step one
\[2m(a^4-16b^8)\]

Answer 3

step two
\[2m(a^2-4b^4)(a^2+4b^4)\]

Answer 4

step 3
\[2m(a-2b)(a+2b)(a^2+4b^4)\]

Answer 5

twice we used factoring the "difference of two squares"
\[x^2-y^2=(x+y)(x-y)\]
