0 = x^{2} - 18 x + 64

x = 9 + 17, x = 9 - 17

Decimal Notation

x = 13.12310 \dots, x = 4.87689 \dots

Solution steps

0 = x^{2} - 18 x + 64

Switch sides

x^{2} - 18 x + 64 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 18 ) \pm ( - 18 ) ^{2} - 4 \cdot 1 \cdot 64}{2 \cdot 1}

(- 18)^{2} - 4 \cdot 1 \cdot 64 = 217

x_{1, 2} = \frac{- ( - 18 ) \pm 2 17}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 18 ) + 2 17}{2 \cdot 1}, x_{2} = \frac{- ( - 18 ) - 2 17}{2 \cdot 1}

x = \frac{- ( - 18 ) + 2 17}{2 \cdot 1} : 9 + 17

x = \frac{- ( - 18 ) - 2 17}{2 \cdot 1} : 9 - 17

The solutions to the quadratic equation are:

x = 9 + 17, x = 9 - 17

x^{2} + 6 x - 100 = 6 x

5 (x + 6)^{2} - 48 = - 28

- 3 x^{2} - 21 x - 30 = 0

d^{2} - 9 d + 2 = 0

x^{2} + 5 x = 0
