Question

Match the column A with column B.

• A. $a\to q;b\to s;c\to r;d\to p$
• B. $a\to s;b\to q;c\to p;d\to r$
• C. $a\to q;b\to s;c\to p;d\to r$
• D. None of these

Answer 1

Answer: (C)

$a\to q;b\to s;c\to p;d\to r$

For an equation $a{x}^2+bx+c=0$, the discriminant $△=b^2-4ac$ helps us understand the nature of the roots.
When $△=0$ roots are real and equal
When $△<0$ roots are complex conjugates
When $△>0$ and a perfect square, roots are rational
When $△>0$ and not a perfect square, roots are irrational
So, Option C is the correct answer.
