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
