Question 1/2 Hard Mathematics Quadratic Equations Roots of a Quadratic Equation Class 10 Level 32

यदि समीकरण (x-2-2(m+2)x+(m+2)2=0) के मूल बराबर हैं तो (m) के लिए क्या सही है?

If roots of (x-2-2(m+2)x+(m+2)2=0) are equal, what is true for (m)?

Explanation opens after your attempt
Correct Answer

A. हर वास्तविक (m)Every real (m)

Step 1

Concept

The equation becomes ((x-(m+2))2=0). Therefore the roots are equal for every real (m).

Step 2

Why this answer is correct

The correct answer is A. हर वास्तविक (m) / Every real (m). The equation becomes ((x-(m+2))2=0). Therefore the roots are equal for every real (m).

Step 3

Exam Tip

समीकरण ((x-(m+2))2=0) बनता है। इसलिए हर वास्तविक (m) के लिए दोनों मूल बराबर होंगे।

Question 2/2 Hard Mathematics Quadratic Equations Roots of a Quadratic Equation Class 10 Level 31

यदि (x-2-2(m+1)x+\(m^2+2m+1\)=0) के मूल बराबर हैं तो (m) के लिए क्या सही है?

If roots of (x-2-2(m+1)x+\(m^2+2m+1\)=0) are equal, what is true for (m)?

Explanation opens after your attempt
Correct Answer

A. हर वास्तविक (m)Every real (m)

Step 1

Concept

The constant term is ((m+1)2), and the equation becomes ((x-(m+1))2=0). Hence roots are equal for every real (m).

Step 2

Why this answer is correct

The correct answer is A. हर वास्तविक (m) / Every real (m). The constant term is ((m+1)2), and the equation becomes ((x-(m+1))2=0). Hence roots are equal for every real (m).

Step 3

Exam Tip

अचर पद ((m+1)2) है और समीकरण ((x-(m+1))2=0) बनता है। इसलिए हर वास्तविक (m) के लिए मूल बराबर हैं।
