Jawaban dari (3x²+10x-7)

[tex]{3x}^{2} + 10x - 7 \\ a = 3 \: \: \: \: \: b = 10 \: \: \: \: \: c = - 7 \\ x = \frac{ - b \frac{ + }{ - } \sqrt{ {b}^{2} - 4ac } }{ 2a} \\ x = \: \frac{ - 10 \frac{ + }{ - } \sqrt{100 - 84} }{6} \\ x = \frac{ - 10 \frac{ + }{ - } \sqrt{16} }{6} \\ x = \frac{ - 10 \frac{ + }{ - }4 }{6} = \frac{ - 5 \frac{ + }{ - } 2}{3} \\ x1 = \frac{ - 5 + 2}{3} = \frac{ - 3}{3} = 1 \\ x2 = \frac{ - 5 - 2}{3} = \frac{ - 7}{3} [/tex]
