what is a2-a factored?

Question

im solving (a) over (a2-1) minus (2a) over (a2-a)
im stuck on the last part tho,what is a2-a factored?

? · Accepted Answer

a2-a =a^2-a =a(a-1)

Wenn · Answer

a (a-1)

Como · Answer

a / ( a ² - 1 ) - (2a) / [ a ( a - 1 ) ]

a /  [ ( a - 1 ) ( a + 1 ) ] - (2a ) / [ a ( a - 1 ) ]

a ² - (2a) ( a + 1 )
------------------------
 a ( a - 1 ) ( a + 1 )

a ² - 2 a ² - 2 a
------------------------
a ( a - 1 ) ( a + 1 )

- a ² - 2 a
-----------------------
a ( a - 1 ) ( a + 1 )

- a ( a + 2 )
-------------------------
a ( a - 1 ) ( a + 1 )

- ( a + 2 )
------------------
( a - 1 ) ( a + 1 )

If by a2-a you mean a(squared)-a it should be a(a-1) Otherwise, I have no clue?

brett · Answer

(a2-a) factored is a(a-1)

? · Answer

a/(a^2 - 1)   -- 2a/(a^2 -a)
a/(a^2 - 1)   -- 2/a-1

(a - 2a+2)/a^2-1

2-a/ a^2 -1

? · Answer

It would be a(a-1)

All you have to do is divide each by a.

Abc · Answer

a² - a

the common element is: a

so, we factor out: a

a² - a = a (a - 1)

So when we have...

2 (a)
________
(a) (a - 1)

... we can cancel out: a.

... and we are left with:

2
____
a - 1
