- 3 a^{2} - 8 a - 5 = 0

a = - \frac{5}{3}, a = - 1

Solution steps

- 3 a^{2} - 8 a - 5 = 0

Solve with the quadratic formula

a_{1, 2} = \frac{- ( - 8 ) \pm ( - 8 ) ^{2} - 4 ( - 3 ) ( - 5 )}{2 ( - 3 )}

(- 8)^{2} - 4 (- 3) (- 5) = 2

a_{1, 2} = \frac{- ( - 8 ) \pm 2}{2 ( - 3 )}

Separate the solutions

a_{1} = \frac{- ( - 8 ) + 2}{2 ( - 3 )}, a_{2} = \frac{- ( - 8 ) - 2}{2 ( - 3 )}

a = \frac{- ( - 8 ) + 2}{2 ( - 3 )} : - \frac{5}{3}

a = \frac{- ( - 8 ) - 2}{2 ( - 3 )} : - 1

The solutions to the quadratic equation are:

a = - \frac{5}{3}, a = - 1

x^{2} + 0 x - 4 = 0

n^{2} - 4 n = 11

x^{2} - 7 x - 34 = 0

x^{2} + 289 = 0

9 x^{2} + 7 x - 56 = 0
