JAMIA 2024 — Mathematics PYQ

Common root $\alpha$ nikalne ke liye hum pehli equation mein se doosri ko subtract karenge:

Step 2: $\alpha$ ki value nikaalein

Ab $(a-b)$ ko common lete hain:

Sawal mein diya gaya hai ki $a\ne b$, iska matlab $a-b\ne 0$ hai. Isliye:

Toh humara common root 1 hai.

Step 3: $(a+b)$ ki value find karein

Ab $\alpha =1$ ki value kisi bhi ek original equation mein rakh dete hain (maan lijiye pehli wali mein):

Final Answer

$a+b$ ki value -1 hai.
