Question

the sum of zeros of the polynomial 2x^- 1x - 3 is​

Answer 1

Step-by-step explanation:

$given \: equation \: is \: 2 {x}^{2} - x - 3 = 0 \\ let \: a = 2 \: \: \: \: \: b = - 1 \: \: \: \: \: \: c = - 3 \\ now \: \\ \: \: \: {b}^{2} - 4ca \\ = 1 + 24 = 25 > 0 \: \\ so \: the \: sum \: of \: zeros \: of \: the \: equation \: is \: 2$
