5 v^{2} + 15 v + 8 = 0

v = \frac{- 15 + 65}{10}, v = \frac{- 15 - 65}{10}

Decimal Notation

v = - 0.69377 \dots, v = - 2.30622 \dots

Solution steps

5 v^{2} + 15 v + 8 = 0

Solve with the quadratic formula

v_{1, 2} = \frac{- 15 \pm 1 5 ^{2} - 4 \cdot 5 \cdot 8}{2 \cdot 5}

1 5^{2} - 4 \cdot 5 \cdot 8 = 65

v_{1, 2} = \frac{- 15 \pm 65}{2 \cdot 5}

Separate the solutions

v_{1} = \frac{- 15 + 65}{2 \cdot 5}, v_{2} = \frac{- 15 - 65}{2 \cdot 5}

v = \frac{- 15 + 65}{2 \cdot 5} : \frac{- 15 + 65}{10}

v = \frac{- 15 - 65}{2 \cdot 5} : \frac{- 15 - 65}{10}

The solutions to the quadratic equation are:

v = \frac{- 15 + 65}{10}, v = \frac{- 15 - 65}{10}

64 x^{2} + 25 = 0

y, y^{2} + 7 b^{2} = 8 b y

x^{2} + 10 x + 25 = 0

- 3 x^{2} - 16 x + 7 = 4

- 2 x^{2} - 8 x - 22 = 0
