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

x = 9, x = - 6

Solution steps

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

Solve with the quadratic formula

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

(- 3)^{2} - 4 \cdot 1 \cdot (- 54) = 15

x_{1, 2} = \frac{- ( - 3 ) \pm 15}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 3 ) + 15}{2 \cdot 1}, x_{2} = \frac{- ( - 3 ) - 15}{2 \cdot 1}

x = \frac{- ( - 3 ) + 15}{2 \cdot 1} : 9

x = \frac{- ( - 3 ) - 15}{2 \cdot 1} : - 6

The solutions to the quadratic equation are:

x = 9, x = - 6

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

z^{2} + 4 z^{6}

6 x^{2} - 36 x + 48

4 1 6^{3}

28 x^{3} - 7 x
