a2-a-20 Factor completely. The 2 is an exponent.

OpenStudy (anonymous):

a x a - a - 20

OpenStudy (anonymous):

each power is how many times you multiply that varriable

OpenStudy (flufflepuffle):

It says to place the factors on the grid and a 4 is in the 9th slot.

OpenStudy (jhannybean):

what are two numbers that multiply to give you 20 but add to give you -1/

OpenStudy (jhannybean):

think about that.

OpenStudy (anonymous):

they want it factored that far??

OpenStudy (flufflepuffle):

Yes.

OpenStudy (jhannybean):

So, @FlufflePuffle ?

OpenStudy (flufflepuffle):

-5 and 4 give you -20 and add up to give you -1 but we need it factored completely. We need to know what to do with the A's.

OpenStudy (jhannybean):

We will get there.

OpenStudy (anonymous):

a x a - a should be already factored

OpenStudy (flufflepuffle):

A times A?

OpenStudy (jhannybean):

so just split the two a's.

OpenStudy (anonymous):

jhanny, it is quite hard to tech how to factor on this website, isn't it?

OpenStudy (jhannybean):

you've already got your two factors, -4 and -5, plug those in
