Suppose P, Q, R are defined as P = a^2b + ab^2 – a^2c – ac^2, Q = b^2c + bc^2 – a^2b – ab^2 & R = a^2c + ac^2 – b^2c – bc^2, where a > b > c - Sarthaks eConnect

Suppose P, Q, R are defined as P = a²b + ab²– a²c – ac², Q = b²c + bc²– a²b – ab² & R = a²c + ac²– b²c – bc², where a > b > c and the equation Px²+ Qx + R = 0 has equal roots, then a, b, c are in

a. A.P

b. G.P

c. H.P

d. AGP
