P:-

$\\ \sf\longmapsto (x+y)^2-4x^2y^2$

$\\ \sf\longmapsto x^2+2xy+y^2-4x^2y^2$

$\\ \sf\longmapsto x^2+y^2-4x^2y^2+2xy$

Q:-

$\\ \sf\longmapsto x^2-2(x+y)-y^2$

$\\ \sf\longmapsto x^2-2x-2y-y^2$

$\\ \sf\longmapsto x^2-y^2-2x-2y$

S:-

$\\ \sf\longmapsto x^2-4x-21+10y-y^2$

$\\ \sf\longmapsto x^2-y^2-4x+10y-21$

T:-

$\\ \sf\longmapsto a^2-10a+24+6b-9b^2$

$\\ \sf\longmapsto a^2-9b^2-10a+6b+24$
