Question

Решите уравнение:
3у^2 - 8у - 3 = 0

Answer 1

D=64+36=100

x1=(8+10)/6=3

x2=(8-10)/6=-(1/3)

Answer 2

$3 {y}^{2} - 8y - 3 = 0 \\ d = {b}^{2} - 4ac = 64 + 36 = 100 \\ x1 = \frac{ - b - \sqrt{d} }{2a} = \frac{8 - 10}{6} = - \frac{1}{3} \\ x2 = \frac{ - b + \sqrt{d} }{2a} = \frac{8 + 10}{6} = 3$
Ответ: x1= -1/3 ; x2=3
