Question

Of one of the Zeroes of polynomial p (x)= (k-1) x²-kx +1 is ​

Answer 1

$\underline{\textbf{Given:}}$

$\textsf{Polynomial is}$

$\mathsf{P(x)=(k-1)x^2-kx+1}$

$\underline{\textbf{To find:}}$

$\textsf{One of the zeroes of P(x)}$

$\underline{\textbf{Solution:}}$

$\mathsf{Consider,}$

$\mathsf{P(x)=(k-1)x^2-kx+1}$

$\mathsf{Sum\;of\;the\;coefficients}$

$\mathsf{=(k-1)-k+1}$

$\mathsf{=0}$

$\therefore\mathsf{x-1\;is\;a\;zero\;of\;P(x)}$

$\underline{\textbf{Find more:}}$

If p(x) =x²-3x+5then the value of p (-2)is​
