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

d = 5 + 25, d = 5 - 25

Decimal Notation

d = 9.47213 \dots, d = 0.52786 \dots

Solution steps

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

Solve with the quadratic formula

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

(- 10)^{2} - 4 \cdot 1 \cdot 5 = 45

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

Separate the solutions

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

d = \frac{- ( - 10 ) + 4 5}{2 \cdot 1} : 5 + 25

d = \frac{- ( - 10 ) - 4 5}{2 \cdot 1} : 5 - 25

The solutions to the quadratic equation are:

d = 5 + 25, d = 5 - 25

2 x + 66 + x = 3 x + 2 + 2 x (4 x)

7 x^{2} - 7 = 0

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

- 5 x^{2} + 8 x - 1 = 0

2 x^{2} + 5 x - 6 = - 3
