Factor away!

I'll show you how to factor the first one but you have to do the rest

5. anonymous

ok

6. Astrophysics

|dw:1436395290243:dw| so here we look at what two numbers add up to 1 and mutliply to give you - 20

7. Astrophysics

That will give you your factors

8. Astrophysics

|dw:1436395334479:dw| also for adding fractions this will come in handy $\frac{ a }{ b } + \frac{ c }{ d } = \frac{ ad+bc }{ bd }$

9. Astrophysics

Now factor everything else

10. Astrophysics

for the second question factor all of it and then remember the dividing by two fractions rule $\frac{ a }{ b } \div \frac{ c }{ d } \implies \frac{ a }{ b } \times \frac{ d }{ c }$

ugh i just dont understand

12. Astrophysics

That's because you need try

13. Astrophysics

If I did the whole problem for you, you wouldn't understand and you would forget, so just try applying what I showed you above, actually for a better guide for factoring you can try https://www.youtube.com/watch?v=eF6zYNzlZKQ
