Jawaban:
[tex] x_{1,2} = (-2, \frac{1}{3}) [/tex]
Penjelasan dengan langkah-langkah:
Kita bisa menggunakan rumus kuadratis :
[tex] x_{1,2} = \frac{-b ± \sqrt{b^2 - 4ac}}{2a} [/tex]
[tex] a = 3[/tex]
[tex] b = 5[/tex]
[tex] c = -2[/tex]
[tex] x_{1,2} = \frac{-5 ± \sqrt{5^2 - 4(3)(-2)}}{2(3)} [/tex]
[tex] = \frac{-5 ± \sqrt{25 + 24}}{6} [/tex]
[tex] x_{1,2} = \frac{-5 ± 7}{6} [/tex]
[tex] x_{1} = \frac{-5 + 7}{6} [/tex]
[tex] x_{1} = \frac{1}{3} [/tex] (penyederhanaan dari 2/6)
[tex] x_{2} = \frac{-5 - 7}{6} [/tex]
[tex] x_{2} = -2 [/tex]
