- 4 x^{2} - 6 x + 54 = 0

x = - \frac{9}{2}, x = 3

Decimal Notation

x = - 4.5, x = 3

Solution steps

- 4 x^{2} - 6 x + 54 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 6 ) \pm ( - 6 ) ^{2} - 4 ( - 4 ) \cdot 54}{2 ( - 4 )}

(- 6)^{2} - 4 (- 4) \cdot 54 = 30

x_{1, 2} = \frac{- ( - 6 ) \pm 30}{2 ( - 4 )}

Separate the solutions

x_{1} = \frac{- ( - 6 ) + 30}{2 ( - 4 )}, x_{2} = \frac{- ( - 6 ) - 30}{2 ( - 4 )}

x = \frac{- ( - 6 ) + 30}{2 ( - 4 )} : - \frac{9}{2}

x = \frac{- ( - 6 ) - 30}{2 ( - 4 )} : 3

The solutions to the quadratic equation are:

x = - \frac{9}{2}, x = 3

9 x^{2} - x - 9 = 0

5 n^{2} - 6 n - 3 = 0

0 = 16 t - 4.9 t^{2}

2 x^{2} = x - 3

z^{2} = 1 + j 3
