- 3 x^{2} - 54 x - 240 = 0

x = - 10, x = - 8

Solution steps

- 3 x^{2} - 54 x - 240 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 54 ) \pm ( - 54 ) ^{2} - 4 ( - 3 ) ( - 240 )}{2 ( - 3 )}

(- 54)^{2} - 4 (- 3) (- 240) = 6

x_{1, 2} = \frac{- ( - 54 ) \pm 6}{2 ( - 3 )}

Separate the solutions

x_{1} = \frac{- ( - 54 ) + 6}{2 ( - 3 )}, x_{2} = \frac{- ( - 54 ) - 6}{2 ( - 3 )}

x = \frac{- ( - 54 ) + 6}{2 ( - 3 )} : - 10

x = \frac{- ( - 54 ) - 6}{2 ( - 3 )} : - 8

The solutions to the quadratic equation are:

x = - 10, x = - 8

\frac{500000}{x ^{2} + 400} < 340

3 (x + 1) < x + 7

\frac{2}{3} + \frac{5}{a}

(2)^{- 1}

5 - 3 x = - 3
