- 5 x^{2} - 80 x - 140 = 0

x = - 14, x = - 2

Solution steps

- 5 x^{2} - 80 x - 140 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 80 ) \pm ( - 80 ) ^{2} - 4 ( - 5 ) ( - 140 )}{2 ( - 5 )}

(- 80)^{2} - 4 (- 5) (- 140) = 60

x_{1, 2} = \frac{- ( - 80 ) \pm 60}{2 ( - 5 )}

Separate the solutions

x_{1} = \frac{- ( - 80 ) + 60}{2 ( - 5 )}, x_{2} = \frac{- ( - 80 ) - 60}{2 ( - 5 )}

x = \frac{- ( - 80 ) + 60}{2 ( - 5 )} : - 14

x = \frac{- ( - 80 ) - 60}{2 ( - 5 )} : - 2

The solutions to the quadratic equation are:

x = - 14, x = - 2

6 x^{2} - 4 x = 2

6 m^{2} + 26 m = 20

3 b^{2} = 1
