समीकरण \(2x^2+4x+2=0\) के लिए विविक्तकर का चिन्ह क्या है?
What is the sign of the discriminant for \(2x^2+4x+2=0\)?
Explanation opens after your attempt
Correct Answer
A. शून्य/zero
Step 1
Concept
(D=42-4(2)(2)=0). So this is the case of equal real roots.
Step 2
Why this answer is correct
The correct answer is A. शून्य / zero. (D=42-4(2)(2)=0). So this is the case of equal real roots.
Step 3
Exam Tip
(D=42-4(2)(2)=0) है। इसलिए यह समान वास्तविक मूलों की स्थिति है।

Question 2/2
Easy Mathematics
Quadratic Equations Nature of Roots Class 10 Level 37
समीकरण \(3x^2-2x+4=0\) के लिए विविक्तकर का चिन्ह क्या है?
What is the sign of the discriminant for \(3x^2-2x+4=0\)?
Explanation opens after your attempt
Correct Answer
A. ऋणात्मक/negative
Step 1
Concept
(D=(-2)2-4(3)(4)=-44<0). Hence the discriminant is negative.
Step 2
Why this answer is correct
The correct answer is A. ऋणात्मक / negative. (D=(-2)2-4(3)(4)=-44<0). Hence the discriminant is negative.
Step 3
Exam Tip
(D=(-2)2-4(3)(4)=-44<0) है। अतः विविक्तकर ऋणात्मक है।
