If (p(x)=kx+2) and (p(0)=2), which statement about (k) is correct so that (p(x)) is linear?
B. \(k\neq0\)
(p(0)=2) हर (k) के लिए सही है। रेखीय होने के लिए \(k\neq0\) जरूरी है। / (p(0)=2) is true for every (k). For the polynomial to be linear, \(k\neq0\) is necessary.

In which option is the sum of two linear polynomials a constant polynomial?
B. (3x+4) और (-3x+5)(3x+4) and (-3x+5)
(3x+4+(-3x+5)=9) है। (x) वाले पद कटने पर नियतांक बहुपद मिलता है। / (3x+4+(-3x+5)=9). When the (x)-terms cancel, a constant polynomial is obtained.
