Answer 2

$Let \: the \: polynomial \: p(x) = 2 - x(x-1)$

/* To find zeroes take p(x) = 0 */

$2 - x(x-1) = 0$

$\implies 2 - x^{2} + x = 0$

$\implies -x^{2} + x + 2 = 0$

/* Compare this with

ax² + bx + c = 0, we get

a = -1 , b = 1 , c = 2

$Product \: of \: zeroes = \frac{c}{a} \\= \frac{2}{-1}\\= -2$

Therefore.,

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