यदि (q(x)=(a+2)x-6+(a-4)x-5+3) की घात ठीक (5) हो, तो (a) का मान क्या होगा?

If (q(x)=(a+2)x-6+(a-4)x-5+3) has degree exactly (5), what is the value of (a)?

Correct Answer

B. (-2)

Explanation

Simple Explanation

घात (5) के लिए \(x^6\) का गुणांक शून्य और \(x^5\) का गुणांक अशून्य होना चाहिए। (a=-2) पर (a-4=-6) अशून्य रहता है। / For degree (5), the \(x^6\) coefficient must be zero and the \(x^5\) coefficient must be non-zero. At (a=-2), (a-4=-6) remains non-zero.

कौन-सा व्यंजक (x) में बहुपद है और (x) की सबसे बड़ी घात (5) है?

Which expression is a polynomial in (x) and has highest power (5)?

Correct Answer

A. \(x^5-2x^2+6\)

Explanation

Simple Explanation

\(x^5-2x^2+6\) में सभी घातें मान्य हैं और सबसे बड़ी घात (5) है। इसलिए यह घात (5) का बहुपद है। / In \(x^5-2x^2+6\), all powers are valid and the highest power is (5). So it is a polynomial of degree (5).
