8x²-288=0eu quero os cálculos passo a passo

Answer 1

$Resolu\c{c}\~ao \to \left\{\begin{array}{ccc}8x^2-288=0\\\\x^2 = \frac{288}{8}\\\\x^2 =36\\\\x = \pm\sqrt{36}\\\\x = \pm\sqrt{6^2}\\\\x = \pm6\\\\\boxed{\boxed{S=\{-6,6\}}} \end{array}\right$

Espero ter ajudado. =^.^=

Answer 2

8x^2-288=0
8x^2=0+288
8x^2=288
