9x^2 -3x+5/36 =0
Resolvendo:
Multiplique todos os coeficientes por 36
(9x^2).36 - (3x).36 + (5/36).36 = 0 . 36
324 x² - 108 x + 5 = 0
Agora aplique a Fórmula de Baskara:
a = 324; b = -108; c = 5
Cálculo do Delta (▲)
▲ = b² - 4ac
▲ = (-108)² - 4(324)(5)
▲ = 11664 - 6480
▲ = 5184
x1 = [(-b) + √▲]/2a = [-(-108) + √5184]/2(324) = [108 + 72]/648
x1 = 180/648 = 5/18
x2 = [(-b) - √▲]/2a = [-(-108) - √5184]/2(324) = [108 - 72]/648
x2 = 36/648 = 1/18
S = {1/18 ; 5/18}
