Question

lf α and β are the roots of ax2+bx+ c=0 then calculate α+β ​

Answer 1

$HEYA \: \\ \\ ax {}^{2} + bx + c = 0 \\ this \: equation \: has \: two \: root \: let \: those \: \\ two \: roots \: be \: \alpha \: \: and \: \: \beta \\ \\ \alpha + \beta = - b \div a \\ \\ and \: \\ \\ \alpha \times \beta = c \div a$
