What are the roots of the quadratic equation 3x2 − 2x − 1 = 0?

Sagot :

 the value of x are 1 and -1/3
The roots are [tex] x_{1} = - \frac{1}{3} [/tex] and [tex] x_{2} = 1[/tex]

Solution:
3x² - 2x - 1 = 0

Solve by factoring:
(3x + 1) (x - 1) = 0

3x + 1 = 0 
3x = -1
3x/3 = -1/3
x = -1/3

x - 1 = 0
x = 1
