Question

if
$\alpha \: and \: \beta \: are \: the \: roots \: of \: the \: quadratic \: equation \: 3x ^{2} + kx + 8 = 0 \: and \ \: \alpha + \beta = 2 \div 3 \: then \: find \: the \: value \: of \: k$
​

Answer 1

Answer:

here k = -2 because as we know that alpha + beta= -b\a and here -b\a is given 2\3 that's why it's -2
