0 = - x^{2} + 6 x - 15

x = 3 - 6 i, x = 3 + 6 i

Solution steps

0 = - x^{2} + 6 x - 15

Switch sides

- x^{2} + 6 x - 15 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 6 \pm 6 ^{2} - 4 ( - 1 ) ( - 15 )}{2 ( - 1 )}

Simplify

6^{2} - 4 (- 1) (- 15) : 26 i

x_{1, 2} = \frac{- 6 \pm 2 6 i}{2 ( - 1 )}

Separate the solutions

x_{1} = \frac{- 6 + 2 6 i}{2 ( - 1 )}, x_{2} = \frac{- 6 - 2 6 i}{2 ( - 1 )}

x = \frac{- 6 + 2 6 i}{2 ( - 1 )} : 3 - 6 i

x = \frac{- 6 - 2 6 i}{2 ( - 1 )} : 3 + 6 i

The solutions to the quadratic equation are:

x = 3 - 6 i, x = 3 + 6 i

x, x^{2} + 3 x = 0

y^{2} - 12 y = - 34

(7 + 2 x) (3 + 2 x) - 21 = 56

0 = 40 + 5 x - 4.9 x^{2}

x, x^{2} + y^{2} = a
