Question

Equação
$\sqrt{2x - 3} - \sqrt{x + 11} = 0$
me ajudem pfv

Answer 1

$\sqrt{2x-3} - \sqrt{x+11} =0 \\ \\ \sqrt{2x-3} = \sqrt{x+11} \\ \\ elevar~~ambos~~membros~~ao~~quadrado \\ \\ ( \sqrt{2x-3} )^2=( \sqrt{x+11} )^2 \\ \\ 2x-3=x+11 \\ \\ 2x-x=11+3 \\ \\ x=14 \\ \\ verificando \\ \\ \sqrt{2.(14)-3} - \sqrt{14+11} =0 \\ \\ \sqrt{28-3} - \sqrt{25} =0 \\ \\ \sqrt{25} -5=0 \\ \\ 5-5=0 \\ \\ 0=0~~V \\ \\ S=\{14\}$
