Question

lf aß be the zeros of the quadratic polynomial
2-3x - xsquare, then a + B -​

Answer 1

$\frac{3}{2}$

Step-by-step explanation:

${x}^{2} - 3x - 2$

$let \: a = 1. \\ b = - 3. \\ c = - 2.$

$let \: \alpha \: and \: \beta \: are \: the \: zeroes \: of \: the \: polynomial.$

$so \: the \: sum \: of \: \alpha \: and \: \beta \: is \: ( \alpha + \beta )$

$( \alpha + \beta ) = - \frac{b}{a}$

$= \: - \frac{( - 3)}{2} \\ = \frac{3}{2}$
