Given:

x² - 5 =  \frac{2x-1}{3}

Multiply each term by their LCD, 3:

3[x² - 5 =  \frac{2x-1}{3} ]3

3x² -15 = 2x - 1

Arrange in standard form:
3x² - 2x - 15 + 1 = 0
3x² - 2x - 14 = 0

Use Quadratic Formula to solve the equation:
a = 3;      b = -2;     c = -14

ANSWER:  

x =  \frac{1}{3}  \frac{1}{3}  \sqrt{43}     and

x =  \frac{1}{3}  \frac{1}{3} \sqrt{43}
