2. d+7/d^2-49

3.t2-25/t^2+t20

4.2x^2+6x+4/4x^212x16

5.6y/y^22y24

Can someone help me with these,please,lol,I'm brain dead

Try to factor where you can, then simplify as much as you can.

I'll show you the first two problems; maybe you can try the rest on your own.

#1. (4x - 12)/4x

Factor the numerator (top).

4(x-3)/4x

We can cancel out 4 in both the numerator and denominator (bottom).

When we do that, we end up with (x-3)/x

#2. (d+7)/(d^2-49)

Factor the denominator.

(d+7)/(d+7)(d-7)

We can cancel out (d+7) in both the numerator and denominator.

When we do that, we end up with 1/(d-7)

I hope this will help get you started on these problems.
