Question

zero of polynomial p(y),where p(y)=by -1, b≠0 is (a)$\frac{1}{b}$ (b) 1 (c)$\frac{5}{b}$

Answer 1

$Given \: polynomial \: p(y) = by - 1, b \neq 0$

$Finding \:a \:zero \:of \:p(y) , is \:the \:same$

$as \: solving \: the\: equation \:p(x) = 0$

$As \: by - 1 = 0$

$\implies by = 1$

$\implies y = \frac{1}{y}$

$So, y = \frac{1}{y} \: zero \: of \: the$

$polynomial\: p(y) = by - 1$

Therefore.,

$Option \: \pink { ( a ) } \: is \: correct.$
