Question

$find \: the \: roots \: of \: {x}^{2} - 3x - 10 = 0$
​

Answer 1

Answer:

$The \ roots \ of \ x^{2} -3x-10=0 \ are \ 5 \ and \ -2$

Step-by-step explanation:

$Given \ quadratic \ equation, \\ x^{2} -3x-10=0 \\\\ => x^{2} +2x-5x-10=0 \\\\=>x(x+2)-5(x+2)=0 \\\\=>(x+2)(x-5)=0 \\\\ >> x+2=0 =>x=-2 \\\\>>x-5=0 =>x=5 \\\\\\ The \ roots \ of \ x^{2} -3x-10=0 \ are \ 5 \ and \ -2$
