Can someone slove these for me

1.(4x-12)/4x

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

3.(t^2-25)/(t^2+t-20)

4.(2x^2+6x+4)/(4x^2-12x-16)

5.(6-y)/*y^2-2y-24)

all you have to do is reduce like #1

4x-12

______

4x

cross out the 4x b/c it's on the top and bottom which leaves just -12 on the top

You can't do that!!!

That is like saying (4 + 5)/4 = 5

(4x-12)/(4x)

= 4(x-3)/(4x)

= (x-3)/x
