समीकरण \(x^2-18x+81=0\) का मूल कौन सा है?
Which is the root of \(x^2-18x+81=0\)?
#roots
#repeated_root
#recognition
A (9) दो बार / (9) twice
B (-9) दो बार / (-9) twice
C (18) दो बार / (18) twice
D (0) दो बार / (0) twice
Explanation opens after your attempt
Correct Answer
A. (9) दो बार / (9) twice
Step 1
Concept
(x-2 -18x+81=(x-9)2 ). Therefore the repeated root is (9).
Step 2
Why this answer is correct
The correct answer is A. (9) दो बार / (9) twice. (x-2 -18x+81=(x-9)2 ). Therefore the repeated root is (9).
Step 3
Exam Tip
(x-2 -18x+81=(x-9)2 ) है। इसलिए दोहराया मूल (9) है।

समीकरण \(x^2+14x+49=0\) का मूल कौन सा है?
Which is the root of \(x^2+14x+49=0\)?
#roots
#repeated_root
#recognition
A (7) दो बार / (7) twice
B (-7) दो बार / (-7) twice
C (14) दो बार / (14) twice
D (0) दो बार / (0) twice
Explanation opens after your attempt
Correct Answer
B. (-7) दो बार / (-7) twice
Step 1
Concept
(x-2 +14x+49=(x+7)2 ). Therefore the repeated root is (-7).
Step 2
Why this answer is correct
The correct answer is B. (-7) दो बार / (-7) twice. (x-2 +14x+49=(x+7)2 ). Therefore the repeated root is (-7).
Step 3
Exam Tip
(x-2 +14x+49=(x+7)2 ) है। इसलिए दोहराया मूल (-7) है।
