0 = - 16 x^{2} + 64 x + 5

x = - \frac{- 8 + 69}{4}, x = \frac{8 + 69}{4}

Solution steps

0 = - 16 x^{2} + 64 x + 5

Switch sides

- 16 x^{2} + 64 x + 5 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 64 \pm 6 4 ^{2} - 4 ( - 16 ) \cdot 5}{2 ( - 16 )}

6 4^{2} - 4 (- 16) \cdot 5 = 869

x_{1, 2} = \frac{- 64 \pm 8 69}{2 ( - 16 )}

Separate the solutions

x_{1} = \frac{- 64 + 8 69}{2 ( - 16 )}, x_{2} = \frac{- 64 - 8 69}{2 ( - 16 )}

x = \frac{- 64 + 8 69}{2 ( - 16 )} : - \frac{- 8 + 69}{4}

x = \frac{- 64 - 8 69}{2 ( - 16 )} : \frac{8 + 69}{4}

The solutions to the quadratic equation are:

x = - \frac{- 8 + 69}{4}, x = \frac{8 + 69}{4}
