x^{2} - 2 x + 81 = 0

x = 1 + 45 i, x = 1 - 45 i

Solution steps

x^{2} - 2 x + 81 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 2 ) \pm ( - 2 ) ^{2} - 4 \cdot 1 \cdot 81}{2 \cdot 1}

Simplify

(- 2)^{2} - 4 \cdot 1 \cdot 81 : 85 i

x_{1, 2} = \frac{- ( - 2 ) \pm 8 5 i}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 2 ) + 8 5 i}{2 \cdot 1}, x_{2} = \frac{- ( - 2 ) - 8 5 i}{2 \cdot 1}

x = \frac{- ( - 2 ) + 8 5 i}{2 \cdot 1} : 1 + 45 i

x = \frac{- ( - 2 ) - 8 5 i}{2 \cdot 1} : 1 - 45 i

The solutions to the quadratic equation are:

x = 1 + 45 i, x = 1 - 45 i

3 x^{2} - 5 x - 1 = 0

- 3 x^{2} - 14 x + 5 = 0

7 (x + 18)^{2} = 2800

(\frac{y ^{2}}{2}) (7.6) = 2.01 (17.5 - y) + 2.01 (10.5 - y)

0 = - 16 x^{2} + 64
