Thank you
in question it is mention that find the value of r1 and r2 without using quadratic eq but u use quadratic equation .any other method to solve this question
Another Approach -
Base 10 $\rightarrow$ Base 16 $\rightarrow$ Base 2 $\rightarrow$ Base 8
you mean binary format?
Yes. By options, we can see that $r_1 \ and \ r_2 $ can be 16 or 8 only.
So conversion from base 10 to base 16 will make everything easy.
