If k1,k2,k3 are real numbers and the equation k1x2+k2x+k3=0 have three roots, then value of k1+k2+k3 is
0
k1x2+k2x+k3=0is a two degree equation if k1≠0, then it should have maximum two roots but given question states it has three roots that's why given equation is an identity equation which means k1=0,k2=0,k3=0.
