Question

if alpha n beta are roots of x2+5x-1=0=10 find alpha+ beta​

Answer 1

$\huge \bold \color{red}answer$

given:- alpha and beta are roots of x²+5x-1 -10= 0

equation is x²+5x-11 = 0

it's in the form of a quadratic equation

ax²+bx+c = 0

we know that..in quadratic equation

$sum \: of \: zeroes = \frac{ - b}{a}$

$so \: alpha + beta = \frac{ - 5}{1}$

hence, alpha + beta = -5
