Question

Help Please! Reduce rational expression,

4x+16                               x-4
______________________ . ______________________
x to the 2 power -16                   x

Thank you.

anonymous · Answer

(4x+16)/(x^2-16) * (x-4)/x ?

anonymous · Answer

yes

anonymous · Answer

You need to simplify each term first. What can 4x+16 be written as?
Similarly, what can x^2-16 be written as? Then, cancel out same terms when they occur in numerator and denominator.

anonymous · Answer

Factor out 4 from 4x+16= 4(x+4)
For x^2-16 use difference of squares =(x-4)(x+4) and follow GT instructions

anonymous · Answer

i got x+4 over x... or is it x+4 over 4x

anonymous · Answer

It should be 4/x.

anonymous · Answer

4(x+4) * (x-4) / (x+4)(x-4)x = 4/x
