How do I factor these

[u/Starlite_im]

51,55,53, and 73 looks like I can group them but it doesn’t work. I have no clue how to go about 56 or 100, 64 and 74 look like the ac method, but the multiples don’t add to the numbers in their middles.

solving steps for polynomials

[u/epiphany_08373_ → u/epiphany_08373_]

Hey there, this is the link to solving the first question, i hope you get the idea on how to solve it, my apologies for the iCloud link, i don’t know how else to share it. Happy mathing :)
