4 x^{2} - 8 x - 60 = 0

x = 5, x = - 3

Solution steps

4 x^{2} - 8 x - 60 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 8 ) \pm ( - 8 ) ^{2} - 4 \cdot 4 ( - 60 )}{2 \cdot 4}

(- 8)^{2} - 4 \cdot 4 (- 60) = 32

x_{1, 2} = \frac{- ( - 8 ) \pm 32}{2 \cdot 4}

Separate the solutions

x_{1} = \frac{- ( - 8 ) + 32}{2 \cdot 4}, x_{2} = \frac{- ( - 8 ) - 32}{2 \cdot 4}

x = \frac{- ( - 8 ) + 32}{2 \cdot 4} : 5

x = \frac{- ( - 8 ) - 32}{2 \cdot 4} : - 3

The solutions to the quadratic equation are:

x = 5, x = - 3

3 d^{2} = - 15

x^{\frac{5}{2}} - 4 x^{\frac{1}{2}}

(1 + i 3)^{3}

\frac{3}{5} \cdot \frac{5}{7}

6 x^{2} + 12 x - 3 = 0
