TO FIND :–

ZERO'S OF GIVEN POLYNOMIAL.

${ \bold{ \huge{ \underline{solution} : - }}} \\ \\ \\ { \bold{ \implies \: {x}^{2} - 2x - 3 = 0 }} \\ \\ \\ { \bold{ \implies \: {x}^{2} - 3x + x - 3 = 0}} \\ \\ \\ { \bold{ \implies \: x(x - 3) + 1(x - 3) = 0 }} \\ \\ \\ { \bold{ \implies \: (x + 1)(x - 3) = 0}} \\ \\ \\ { \bold{ \implies \:x = - 1 \: \: and \: \: x = 3 }}$
