Question

f(x) = x² - $\sqrt{3x}$

Answer 1

Resposta:

$f(x)=x^2-\sqrt{3x} \\ \\ x^{2} =\sqrt{3x}$

eleva ao quadrado ambos os membros

$(x^2)^2=(\sqrt{3x} )^2\\ \\ x^4=3x\\ \\ \\x^4-3x=0\\ \\ fatorar\\ \\ x(x^3-3)=0\\ \\ x^3-3=0~~~~~~~~~~~e~~~~~~~x=0\\ \\ x^3=3\\ \\ \\x=\sqrt[3]{3} \\ \\ \\ S=\{0,\sqrt[3]{3}\}$
