x^{2} + 15 x + 8 = 0

x = \frac{- 15 + 193}{2}, x = \frac{- 15 - 193}{2}

Decimal Notation

x = - 0.55377 \dots, x = - 14.44622 \dots

Solution steps

x^{2} + 15 x + 8 = 0

Solve with the quadratic formula

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

1 5^{2} - 4 \cdot 1 \cdot 8 = 193

x_{1, 2} = \frac{- 15 \pm 193}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 15 + 193}{2 \cdot 1}, x_{2} = \frac{- 15 - 193}{2 \cdot 1}

x = \frac{- 15 + 193}{2 \cdot 1} : \frac{- 15 + 193}{2}

x = \frac{- 15 - 193}{2 \cdot 1} : \frac{- 15 - 193}{2}

The solutions to the quadratic equation are:

x = \frac{- 15 + 193}{2}, x = \frac{- 15 - 193}{2}

x^{2} - 11 x + 18

f = (\frac{3}{2})^{5}

\frac{16 !}{( 16 - 5 ) ! 5 !} 0. 5^{5} 0. 5^{16 - 5}

(5 - 11) (5 + 11)

7 ∣ 3 - 8 x ∣ = 28
