x^2-25/20x-4x^2 reduced

Question

campbell_st · Answer

start by factoring the numerator and denominator... 


the numerator is the difference of 2 squares

the denominator, take out a common factor if -4x.... this will reverse the order and make it easier to see the common factor between the numerator and denominator.

I did, but I (x+5)(x-5) / 2x(10-2x)
Is that the answer or does it still need to be reduced

campbell_st · Answer

ok... well in your the denominator, both terms are even... and so have a common factor of 2..., which means it can become

4x(5 - x)

if you take a common factor of -1, it reverses the order within the brackets

-4x(x - 5)

now the common factor, that can be removed from the fraction, is more obvious
