Answer 1

A iS the answer i got it right on my test

Explanation:

Y-4/Y-5

Answer 2

The correct option is C

Explanation:

The given expression is:

=y²+7y+12/y²-3y-18

Break the middle term of both the numerator and denominator:

=y²+4y+3y+12/y²-6y+3y-18

Take the common from the expressions:

=y(y+4)+3(y+4)/y(y-6)+3(y-6)

=(y+3)(y+4)/(y+3)(y-6)

The same terms will be cancelled: Then we have,

=(y+4)/(y-6)

Therefore the correct option is C....
