57quad " If "p=(4xy)/(x+y)," find the value of "(p+2x)/(p-2x)+(p+2y)/(p-2y)

If p(y) =y(y-1)(y+2) then find the value of p(0)+p(1)+p(-2)

If x=(p+q)/(p-q) and y=(p-q)/(p+q) then the value of (x-y)/(x+y) is

If x=(sin p)/(cos^(2)p),y=(cos p)/(sin^(2)p) and sin p+cos p=(1)/(2) ,then find the value of (44)/((x+y))

If x= 3p and y=(2p)/5+1 , then find the value of p for which x = 5y.

In P=(5x+2y)/(3x-4y) , if x=5 and P=7, the y=?
