ok..the way i thought was taking the negative reciprocal of the denominator..
making it (4-1/x)(4-1/x)
---------------
(4+1/x)(4-1/x)
=16-8 1/x+1/x^2
----------------
16-1/x^2
does that work?
I haven't been taught how the...
I am in grade 11 mathematics...i got this as a Thinking & Problem Solving Q..can someone simplify this, step by step?
4 - 1/x
---------
4 + 1/x
THANKS!
