Simplify the complex fraction. y-1/y^2+y-6/y-6/y+3 a) (y-1)(y-2)/(y-6)(y+2) b) y-1/(y-6)(y-2) c) (y-1)(y-6)/(y+3)^2 (y-2) d) (y-1)(y-6)/(y+3)(y-2) i really need on this

For this case we have the following complex fraction:
 
 Using the double C method, we can rewrite the given fraction.
 We have then:
 
 Then, we must factor the quadratic expression into the denominator.
 We have then:
 
 Finally, we cancel similar terms.
 We have then:
 
 
 the complex fraction simplified is:
 B) y-1/(y-6)(y-2)
