Answer 1

2nd link i don't get it i think its already factorised and simplified.


1st link, we have -

(x-6)/ ( x2-4x-32) x (x-4)/x+2 x (x-6)/(x+8)(x+2)

(If 2nd link means same prob. as 1st link)


So 1st we factorise x2+4x-32

=> x2+8x-4x-32

x(x+8)-4(x+8)

=> (x-4)(x+8)

We hence have -

(x-6) (x-4) (x-6)
_________ x __________ x __________
(x-4)(x+8) (x+2) (x+8)(x+2)

Which on simplifying gives -


1
_________
(x+8)(x+8)(x+2)(x+2)
