- d^{2} + 10 d + 5 = 0

d = 5 - 30, d = 5 + 30

Decimal Notation

d = - 0.47722 \dots, d = 10.47722 \dots

Solution steps

- d^{2} + 10 d + 5 = 0

Solve with the quadratic formula

d_{1, 2} = \frac{- 10 \pm 1 0 ^{2} - 4 ( - 1 ) \cdot 5}{2 ( - 1 )}

1 0^{2} - 4 (- 1) \cdot 5 = 230

d_{1, 2} = \frac{- 10 \pm 2 30}{2 ( - 1 )}

Separate the solutions

d_{1} = \frac{- 10 + 2 30}{2 ( - 1 )}, d_{2} = \frac{- 10 - 2 30}{2 ( - 1 )}

d = \frac{- 10 + 2 30}{2 ( - 1 )} : 5 - 30

d = \frac{- 10 - 2 30}{2 ( - 1 )} : 5 + 30

The solutions to the quadratic equation are:

d = 5 - 30, d = 5 + 30

10 ∣ 4 x - 8 ∣ - 8 = 72

\frac{19 !}{( 19 - 4 ) ! 4 !}

5 < 3 y + 11 \leq 11
