यदि (p(x)=(a-2)x-3+5x-7) और (a=2), तो (p(x)) किस प्रकार का बहुपद बनेगा?
If (p(x)=(a-2)x-3+5x-7) and (a=2), what type of polynomial will (p(x)) become?
Explanation opens after your attempt
C. रेखीय बहुपदLinear polynomial
Concept
Putting (a=2) makes the coefficient of \(x^3\) equal to (0), leaving (5x-7). So it is a linear polynomial.
Why this answer is correct
The correct answer is C. रेखीय बहुपद / Linear polynomial. Putting (a=2) makes the coefficient of \(x^3\) equal to (0), leaving (5x-7). So it is a linear polynomial.
Exam Tip
(a=2) रखने पर \(x^3\) का गुणांक (0) हो जाता है और (5x-7) बचता है। इसलिए यह रेखीय बहुपद है।
