यदि ((t-1)x-3+(t+2)x-2+4) की डिग्री (2) है, तो (t) का सही मान कौन सा हो सकता है?

If the degree of ((t-1)x-3+(t+2)x-2+4) is (2), which value of (t) can be correct?

Explanation opens after your attempt
Correct Answer

A. (t=1)

Step 1

Concept

For degree (2), the \(x^3\) term must vanish and the \(x^2\) term must remain. At (t=1), both conditions hold.

Step 2

Why this answer is correct

The correct answer is A. (t=1). For degree (2), the \(x^3\) term must vanish and the \(x^2\) term must remain. At (t=1), both conditions hold.

Step 3

Exam Tip

डिग्री (2) के लिए \(x^3\) पद हटना चाहिए और \(x^2\) पद बचना चाहिए। (t=1) पर दोनों शर्तें पूरी होती हैं।
