Can someone break down how to do this problem?
Find the Quotient
(25b^2-64)/(5b-8)

anonymous · Answer

usually you wannt to factor it :) the top and bottom if you can

in this case i think bottom is factored for you :).

anonymous · Answer

or i mean bottom cant be factored further

anonymous · Answer

ok... ? lol

anonymous · Answer

oh ok

aravindg · Answer

hint:(a+b)(a-b)

anonymous · Answer

hint: usually in these problems   the bottom is a factor of the top

meaning 5b-8 is a factor of the numerator.

(5*b-8)*(5*b+8)  is the numerator factored out

@AravindG but i have to divide... ?

aravindg · Answer

look at numerator it is of form a^2-b^2

anonymous · Answer

(5*b-8)*(5*b+8) 
-----------------
(5b-8)     

the (5b-8)  cancels so you left with     (5*b+8)   as answer

aravindg · Answer

$$a^2-b^2=(a+b)(a-b)$$
