start by factoring the first two terms 2x + 8 what is the GCF?
i think 2
L.C.M would be 2
right, 2, so we factor out 2 to get 2(x+4)
then we move to the next two terms bx + 4b GCF = ?
right, so we factor out b to get b(x+4) now let's put everything back together 2(x+4) + b(x+4) now, when we have an expression like A*B + C*B we can rewrite it as (A+C)*B so 2(x+4) + b(x+4) = (2+b)(x+4)
and that's it
thnxs a lot mate
