a) Both roots are equal if and only if 10m - 3n+ 14 = 0
b) Both roots are equal if 10m – 3n + 14 = 0
c) Both roots are equal if m=n= -2
d) Discriminant is 91 if m=n= -1
e) Both roots will always be distinct and real if m=n
f) Discriminant is 91 if m=n=4​

Answer 1

Step-by-step explanation:

. Ifa st. line passes through the point(1/5,1/5) and ab=1/6

where a, b are the intercepts of the line on the

co-ordinate axes, then the equation of the line
