Answer 1

Answer:

Step-by-step explanation:

Discriminant of P(x) ;D`=b^2-4ac and that of Q(x) D"=d^2+4acWe are given that ac not equal to 0 .thus ac can either be -ve or + ve.If ac is -ve D` is +ve while D" can be -ve or + veAnd if ac is +ve D" is + ve and D` can be + ve or - ve.For both the cases P(x)Q(x)=0 has at least two real roots
