I hope this answer will help you .

Step-by-step explanation:

For the quadratic equation ax

2

+bx+c=0,a,b,c,εQ

Roots are given by

α=

2a

−b+

b

2

−4ac

and

β=

2a

−b−

b

2

−4ac

If D=0 then α=

2a

−b

=β i.e. the roots are equal and real.

Since a,b and c∈Q, the roots will be equal and rational.

Hence, statements P and R are correct.
