For what value of p the equation (1 + p) x2 + 2(1 + 2p) x + (1 + p) = 0 has coincident roots

For what value of p the equation (1 + p) x2 + 2(1 + 2p) x + (1 + p) = 0 has coincident roots

A quadratic equation has equal roots if and only if its discriminant =0

a=1+p; b= 2+4p; c= 1+p

when a quadratic eqn have coincident roots or 2 = real roots, then there is a relation

b2-4ac = 0

by putting the values , you can get the ans.
