समीकरण \(x^2-3x-1=0\) के मूलों की प्रकृति बताइए।

State the nature of roots of \(x^2-3x-1=0\).

Explanation opens after your attempt
Correct Answer

A. दो वास्तविक अपरिमेय और असमान ((D=13))Two real irrational and distinct ((D=13))

Step 1

Concept

Here (D=(-3)2-4(1)(-1)=13). Since (13) is not a perfect square, the roots are irrational.

Step 2

Why this answer is correct

The correct answer is A. दो वास्तविक अपरिमेय और असमान ((D=13)) / Two real irrational and distinct ((D=13)). Here (D=(-3)2-4(1)(-1)=13). Since (13) is not a perfect square, the roots are irrational.

Step 3

Exam Tip

यहाँ (D=(-3)2-4(1)(-1)=13) है। (13) पूर्ण वर्ग नहीं है, इसलिए मूल अपरिमेय हैं।

समीकरण \(3x^2+5x-2=0\) के लिए सही मूल प्रकृति चुनिए।

Choose the correct root nature for \(3x^2+5x-2=0\).

Explanation opens after your attempt
Correct Answer

A. दो वास्तविक परिमेय और असमान ((D=49))Two real rational and distinct ((D=49))

Step 1

Concept

Here (D=52-4(3)(-2)=49). (D=49) gives two rational distinct roots.

Step 2

Why this answer is correct

The correct answer is A. दो वास्तविक परिमेय और असमान ((D=49)) / Two real rational and distinct ((D=49)). Here (D=52-4(3)(-2)=49). (D=49) gives two rational distinct roots.

Step 3

Exam Tip

यहाँ (D=52-4(3)(-2)=49) है। (D=49) से दो परिमेय असमान मूल मिलते हैं।
