I have no clue how to factor, which seems to be a big chunk of what's going to be on my exam.
I have one problem done that I THINK I did right, but I'm not sure.
y(b+9)+5(b+9)
=(y+5)(b+9)
I don't know if that's right or not, but I remember my teacher saying something like "factor by grouping" and it looking similar to that.
I have a number of other problems from the study guide that I simply do not even know where to begin with. I'll list two.
1. z^2+7zy+5z+35y
2. 7x^2-70x+147
Any help on the steps to do these would be greatly appreciated!
