Question

Factor by grouping:
yw+5w-7y-35

Answer 1

w(y+5)-7(y+5).. do you see this step?

Answer 2

How did you get that? I'm sorry, but I'm unsure of how to do it.

Answer 3

ok if we just look at yw+5w ... there is a w common in both terms. This means you can factor it out. (Essentially, you are dividing the inside of the parentheses by w, and bringing that w out):

w(y+5) ... think if you had to multiply this out, you would get wy+ w5 (or yw+5w) which is what you had initially

Answer 4

Thanks so much!

Answer 5

Ok.. but it's not quite finished, there is just one more step to go for the final solution, can you figure it out?
