यदि (p(x)=x-2-14x+45), तो शून्यकों का प्रकार क्या है?

If (p(x)=x-2-14x+45), what is the type of its zeroes?

Explanation opens after your attempt
Correct Answer

A. वास्तविक परिमेयReal rational

Step 1

Concept

The discriminant is (196-180=16) and \(\sqrt{16}=4\) is rational. Hence the zeroes are real rational.

Step 2

Why this answer is correct

The correct answer is A. वास्तविक परिमेय / Real rational. The discriminant is (196-180=16) and \(\sqrt{16}=4\) is rational. Hence the zeroes are real rational.

Step 3

Exam Tip

विविक्तकर (196-180=16) है और \(\sqrt{16}=4\) परिमेय है। इसलिए शून्यक वास्तविक परिमेय हैं।
