- 3 x^{2} - 51 x - 216 = 0

x = - 9, x = - 8

Solution steps

- 3 x^{2} - 51 x - 216 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 51 ) \pm ( - 51 ) ^{2} - 4 ( - 3 ) ( - 216 )}{2 ( - 3 )}

(- 51)^{2} - 4 (- 3) (- 216) = 3

x_{1, 2} = \frac{- ( - 51 ) \pm 3}{2 ( - 3 )}

Separate the solutions

x_{1} = \frac{- ( - 51 ) + 3}{2 ( - 3 )}, x_{2} = \frac{- ( - 51 ) - 3}{2 ( - 3 )}

x = \frac{- ( - 51 ) + 3}{2 ( - 3 )} : - 9

x = \frac{- ( - 51 ) - 3}{2 ( - 3 )} : - 8

The solutions to the quadratic equation are:

x = - 9, x = - 8

6 (x + 12) = x^{2}

m^{2} + 6 m + 18 = 0

x^{2} + 7 x + \frac{49}{4} = 4

(x + 5)^{2} = 10 x + 50

3 x (5 - x) = x (7 - x)
