x^{2} - 18 x + 74 = 0

x = 9 + 7, x = 9 - 7

Decimal Notation

x = 11.64575 \dots, x = 6.35424 \dots

Solution steps

x^{2} - 18 x + 74 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 18 ) \pm ( - 18 ) ^{2} - 4 \cdot 1 \cdot 74}{2 \cdot 1}

(- 18)^{2} - 4 \cdot 1 \cdot 74 = 27

x_{1, 2} = \frac{- ( - 18 ) \pm 2 7}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 18 ) + 2 7}{2 \cdot 1}, x_{2} = \frac{- ( - 18 ) - 2 7}{2 \cdot 1}

x = \frac{- ( - 18 ) + 2 7}{2 \cdot 1} : 9 + 7

x = \frac{- ( - 18 ) - 2 7}{2 \cdot 1} : 9 - 7

The solutions to the quadratic equation are:

x = 9 + 7, x = 9 - 7

- 5 x^{3} + 65 x^{2} + 150 x

2 x + 3 x + 50 = 180

6 k^{2} + 7 k + 1 = 0

- \frac{1}{5} 275

6 x^{2} + 4 x - 2
