I have also copied the answers here:
2y+1/y^2-y-6
I will assume this is (2y+1)/(y^2-y-6)
First factor the denominator: (y+3)(y-2)
Since there is no common term, this is already simplified.
A^2-b^2/a-b
I will assume this is (a^2-b^2)/(a-b)
First factor the numerator: (a+b)(a-b)
There is an a-b in both numerator and denominator, so this becomes
(a+b)/1=a+b
4x^2/2*9
2*9=18 so we have (4x^2)/18
Divide top and bottom by 2
