Question

the quadratic equation x^2-x-2 has roots which are

Answer 1

${\red {{\bold{ \huge \dag }}\bold {\huge{{\mathcal {\underline{Answer}}}} \dag}}}$

$\star \: \: \underline \blue{solution} \blue{ : }$

$\bold{ {x}^{2} - x - 2 = 0}$

$\longrightarrow \: {x}^{2} - 2x + x - 2 = 0$

$\longrightarrow x(x - 2) + 1(x - 2)=0$

$\longrightarrow \: (x - 2)(x + 1)=0$

$\longrightarrow \: \boxed{\mathfrak {{x=2 \: \: or \: \: x=-1}}}$

HOPE THIS IS HELPFUL
