a^{2} + 14 a + 63 = 8

a = - 7 + 6 i, a = - 7 - 6 i

Solution steps

a^{2} + 14 a + 63 = 8

Move

8

to the left side

a^{2} + 14 a + 55 = 0

Solve with the quadratic formula

a_{1, 2} = \frac{- 14 \pm 1 4 ^{2} - 4 \cdot 1 \cdot 55}{2 \cdot 1}

Simplify

1 4^{2} - 4 \cdot 1 \cdot 55 : 26 i

a_{1, 2} = \frac{- 14 \pm 2 6 i}{2 \cdot 1}

Separate the solutions

a_{1} = \frac{- 14 + 2 6 i}{2 \cdot 1}, a_{2} = \frac{- 14 - 2 6 i}{2 \cdot 1}

a = \frac{- 14 + 2 6 i}{2 \cdot 1} : - 7 + 6 i

a = \frac{- 14 - 2 6 i}{2 \cdot 1} : - 7 - 6 i

The solutions to the quadratic equation are:

a = - 7 + 6 i, a = - 7 - 6 i

\frac{x ^{2} - 4 x}{x + 5} > 0

(- 4 a^{2}) (2 a^{- 3})^{- 4}

8 + x > 31

2 \cdot 5 - 2 \cdot 5 + 2 \cdot 2 \cdot 5 + 10

z + z = 4
