For which value will ((a+2)x+a) be linear and still have (p(0)=a)?
B. (a=0)
रेखीय होने के लिए \(a+2\neq0\) चाहिए। (a=0) पर गुणांक (2) है और (p(0)=0) रहता है। / For it to be linear, \(a+2\neq0\) is needed. At (a=0), the coefficient is (2) and (p(0)=0).

If (p(x)=\frac{3}{4}x-6), what is (p(8))?
A. (0)
(p(8)=\frac{3}{4}\cdot8-6=0) है। इसलिए (8) इस बहुपद का शून्यक है। / (p(8)=\frac{3}{4}\cdot8-6=0). Therefore (8) is a zero of this polynomial.

If (p(x)=x+3), what type of polynomial is (p(x)2)?
B. द्विघात बहुपदQuadratic polynomial
(p(x)2=(x+3)2) की डिग्री (2) होती है। इसलिए यह द्विघात बहुपद है। / (p(x)2=(x+3)2) has degree (2). Therefore it is a quadratic polynomial.

Which option has a linear polynomial whose leading coefficient is not (0)?
B. (5x+0)
(5x+0) में (x) का गुणांक (5) है जो शून्य नहीं है। इसलिए यह रेखीय बहुपद है। / In (5x+0), the coefficient of (x) is (5), which is non-zero. Therefore it is a linear polynomial.

If (p(x)=2x+b) and (p(3)=p(1)+8), what is correct about (b)?
B. हर (b) सही हैEvery (b) is valid
(p(3)-p(1)=(6+b)-(2+b)=4) होता है। इसलिए दी गई शर्त (8) के लिए कभी सही नहीं होती। / (p(3)-p(1)=(6+b)-(2+b)=4). Therefore the given condition for (8) is never true.
