`|(x,p,q),(p,x,q),(q,q,x)| =`

|(x,p,q),(p,x,q),(p,q,x)| =

|(x,p,q),(p,x,q),(p,q,x)|=

Prove that |(x,p,q),(p,x,q),(p,q,x)| = (x - p)(x - q)(x + p +q)

Show that |(x,p,q),(p,x,x),(q,q,x)| = (x - p)(x^(2) + px - 2q^2)

The value of {:[(x,p,q),(p,x,q),(p,q,x)]:} is

If p and q are distinct reals,then 2{(x-p)(x-q)+(p-x)(p-q)+(q-x)(q-p)}=(p-q)^(2)+(x-p)^(2)+(x-q)^(2) is satisfied by no value of x(B) exactly one value of x(C) exactly two value of x(D) infinite values of x

The lines (p-q)x+(q-r)y+(r-p)=0(q-r)x+(r-p)y+(p-q)=0,(x-p)x+(p-q)y+(q-r)=

If f(x)=(q(x-p))/(q-p)+(p(x-q))/(p-q),....pneq, find: f(p)+f(q).

The lines (p-q)x+(q-r)y+(r-p)=0(q-r)x+(r-p)y+(p-q)=0 (r-p)x+(p-q)y+(q-r)=0

Show that: |x p q p x q q q x|=(x-p)(x^2+p x-2q^2)dot
