: I need some help with multipling rational expressions.
Can you please help.
The directions are multiply and state any restrictions on the varibale.
((4x^2)/(5y)) * ((7y)/(12x^4))
((8y-4)/(10y-5)) * ((5y-15)/(3y-9))
((x^(2)-4)/(x^(2)-1)) * ((x+1)/(x^(2)+2x))
Thankyou so much This question is from textbook

1. ((4x^2)/(5y)) * ((7y)/(12x^4))
sol :: 7 /( 15 x^2)
2. ((8y-4)/(10y-5)) * ((5y-15)/(3y-9))
sol :: 4/3

3. ((x^(2)-4)/(x^(2)-1)) * ((x+1)/(x^(2)+2x))

sol :: (x-2)/(x)(x-1)
