Question

trying to reduce to simpilest form

1.t-a/t^2-a^2 i have 1/2(t+a)
2.3y^3+7y^2+4y/y^2+5y+4 i have cannot reduce thanks

Answer 1

first one you should have had

(t-a)/((t+a)(t-a))
= 1/(t+a), I don't know where you got the 1/2 from

for the second one, it factors

y(3y+4)(y+1)/((y+1)(y+4))

let me know what you got

Answer 2

thanks i got could't reduce on the second one the first one the denominator both numbers are to the second power does that matter
