Which equation will have two real and equal roots?
Explanation opens after your attempt
Correct Answer
A. \(x^2+10x+25=0\)
Concept
In the first equation, (D=102-4(1)(25)=0). A perfect square form often gives equal roots.
Why this answer is correct
The correct answer is A. \(x^2+10x+25=0\). In the first equation, (D=102-4(1)(25)=0). A perfect square form often gives equal roots.
Exam Tip
पहले समीकरण में (D=102-4(1)(25)=0) है। पूर्ण वर्ग रूप अक्सर समान मूल देता है।
