# How do you solve 3x^2 − 11x + 8 = 0?

Apr 6, 2016

#### Answer:

1 and $\frac{c}{a} = \frac{8}{3}$

#### Explanation:

$y = 3 {x}^{2} - 11 x + 8.$
Since (a + b + c = 0), use shortcut.
The 2 real roots are: (1) and $\left(\frac{c}{a} = \frac{8}{3}\right)$

Reminder of Shorcut.
- When a + b + c = 0 --> 2 real roots: 1 and $\left(\frac{c}{a}\right)$

• When a - b + c = 0 --> 2 real roots: (-1) and $\left(- \frac{c}{a}\right)$
