Question

if a, b be the zeroes of the polynomial 2- 3x -x^2 then find the value of a + b​

Answer 1

Answer:

$given \: polynomial \: is \\ - {x}^{2} - 3x + 2 \\ equating \: it \: with \: a{x}^{2} + bx + c \\ a = - 1 \\ b = - 3 \\ c = 2 \\ since \: \alpha \: and \: \beta are \: zeros \: of \: given \: polynomial \\ therefore \\ \alpha + \beta = - \frac{b}{a} = - \frac{ - 3}{ - 1} = - 3$
