Simplifying Rational Expressions

1. 4x12/4x
2. d+7/d^249
3.t225/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(x3)/4x
We can cancel out 4 in both the numerator and denominator (bottom).
When we do that, we end up with (x3)/x
#2. (d+7)/(d^249)
Factor the denominator.
(d+7)/(d+7)(d7)
We can cancel out (d+7) in both the numerator and denominator.
When we do that, we end up with 1/(d7)
I hope this will help get you started on these problems.
