I am having a problem solving these problems could you please help me! Simplify by removing the factor of 1, y^2-25/5-y, 4y-12/4y

Answer 1

In the first, change it to

-(y^2-25)/(y-5) then factor the numberator as a difference of two squares (y+5)(y-5)

On the second, notice you can factor 4 out of the numerator, and the denominator, (then the 4/4 becomes 1)
