x^{2} - 18 x + 73 = 0

x = 9 + 22, x = 9 - 22

Decimal Notation

x = 11.82842 \dots, x = 6.17157 \dots

Solution steps

x^{2} - 18 x + 73 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 18 ) \pm ( - 18 ) ^{2} - 4 \cdot 1 \cdot 73}{2 \cdot 1}

(- 18)^{2} - 4 \cdot 1 \cdot 73 = 42

x_{1, 2} = \frac{- ( - 18 ) \pm 4 2}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 18 ) + 4 2}{2 \cdot 1}, x_{2} = \frac{- ( - 18 ) - 4 2}{2 \cdot 1}

x = \frac{- ( - 18 ) + 4 2}{2 \cdot 1} : 9 + 22

x = \frac{- ( - 18 ) - 4 2}{2 \cdot 1} : 9 - 22

The solutions to the quadratic equation are:

x = 9 + 22, x = 9 - 22

25 x^{2} - 15 x = 0

x^{2} - 10 x + 15 = 0

- x^{2} + 11 x - 28 = 0

2 x^{2} - 12 x + 6 = 0

s^{2} + 40 s + 400 = 0
