Factor by grouping: yw+5w-7y-35
w(y+5)-7(y+5).. do you see this step?
How did you get that? I'm sorry, but I'm unsure of how to do it.
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
Ok.. but it's not quite finished, there is just one more step to go for the final solution, can you figure it out?
