For which polynomial is (x=2) a zero?
A. (p(x)=x-2)
(p(2)=2-2=0), इसलिए (x=2) इसका शून्य है। शून्य जांचने के लिए मान रखकर (0) देखें। / (p(2)=2-2=0), so (x=2) is its zero. To test a zero, substitute and check for (0).

For (p(x)=x-2+2x-8), what is (p(2))?
A. (0)
(p(2)=4+4-8=0)। इसलिए (2) इस बहुपद का शून्य है। / (p(2)=4+4-8=0). Hence (2) is a zero of this polynomial.

If \(a\ne0\) in a linear polynomial (ax+b), what is its degree?
B. (1)
(ax+b) में \(a\ne0\) होने पर (x) की सबसे बड़ी घात (1) है। इसलिए घात (1) होगी। / When \(a\ne0\) in (ax+b), the highest power of (x) is (1). So the degree is (1).
