wow you get a lot of attention!

specek18 · Answer

@misty1212 i guess...i'm horrible at math is all, nothing special.

anonymous · Answer

We already factored one of them before.

misty1212 · Answer

you gotta factor both denominators 
$$a^2+4a+4$$ and 
$$a^2-3a-10$$

misty1212 · Answer

@wio i bet it was the perfect square right?
 $a^2+4a+4=(a+2)(a+2)$

specek18 · Answer

you did that so fast....@misty1212

misty1212 · Answer

so what is left is to factor 
$$a^2-3a-10$$ which will definitely have a factor of $a+2$ in it

specek18 · Answer

lol but i'm still writing it out...i did get/ understand what you got!

fibonaccichick666 · Answer

You just learned how to do this from wio, please show us your attempts

misty1212 · Answer

that means the second one is going to be $$(a+2)(binomial)$$ i am sure you can find it without too much agony

fibonaccichick666 · Answer

Please let them try @misty1212 , you are doing the problem for them.

specek18 · Answer

(a+2) again?

misty1212 · Answer

ok bye

anonymous · Answer

They are assuming that $a+2$ is going to be the GCD.

anonymous · Answer

GCF

fibonaccichick666 · Answer

Well, what did you factor both of them into?

anonymous · Answer

But if you didn't make that assumption, you would factor $-10$.

anonymous · Answer

We want $ab=-10$ and $a+b=-3$.

specek18 · Answer

(a+2) (a-5)? after being factored??

anonymous · Answer

Yes

specek18 · Answer

then what....?

anonymous · Answer

Now, what is the GCF?

fibonaccichick666 · Answer

(what term goes into both factorizations?)

undeadknight26 · Answer

Isnt it just that?  Im actually rusty on these things myself...just asking the smart peoples ._.
