Question

Resolva:

1/2 x² = - 32 = 0

Answer 1

$\frac{1}{2} x^{2} -32=0\\ \\ \frac{1}{2} x^{2} =32\\ \\ x^{2} = \frac{32}{1/2}\\ \\ x^{2} =64\\ x= \sqrt{64}\\ x=\pm8\\ \\ \\ \boxed{\boxed{S=\{-8,~8\}}}$


Espero ter ajudado e tenha ótimos estudos :)

Answer 2

$\frac{1x^2}{2} -32=0\\ \\ \frac{1x^2}{2}=32\\ \\x^2=64\\x=\pm \sqrt{64} \\x=\pm8$
