Expert Mathematics Quadratic Equations Class 10 Level 31

यदि (x-2+(m-5)x+9=0) की जड़ें बराबर पर विपरीत चिह्न वाली नहीं हैं और समान हैं, तो (m) के मान क्या हैं?

If (x-2+(m-5)x+9=0) has equal roots that are not of opposite signs, what are the values of (m)?

Correct Answer

A. (11) और (-1)(11) and (-1)

Step 1

Concept

For equal roots, ((m-5)2-36=0). Thus \(m-5=\pm6\), so (m=11) or (m=-1).

Step 2

Why this answer is correct

The correct answer is A. (11) और (-1) / (11) and (-1). For equal roots, ((m-5)2-36=0). Thus \(m-5=\pm6\), so (m=11) or (m=-1).

Step 3

Exam Tip

समान जड़ों के लिए ((m-5)2-36=0) होगा। इसलिए \(m-5=\pm6\), अतः (m=11) या (m=-1)।
