R: x = -3 ou x = 3
4x² - 36 = 0
4x² = 36
x² = 9
raiz de 9 = ±3 rm

4 xx - 36 = 0
4xx = 36
xx = 36/4
xx = 9
x = Raiz quadrade de 9
x = 3 e - 3

4x² - 36 = 0
4x² = 36
x² = 36/4
x² = 9
x = ± √9
x, = 3
x,, = -3
Portanto, o conjunto solução é:
S = {-3,3}

Báscara!
(Delta)= b2 - 4ac
x= -b + - raiz de (delta) / 2a
acho que esta é a formula correta! ela é generica p/ todas as equações de segundo grau! só o "a" não ser zero!
espero ter ajudado!
