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.
