x (x + 8) + 2900 = 0

x = - 4 + 2721 i, x = - 4 - 2721 i

Solution steps

x (x + 8) + 2900 = 0

Expand

x (x + 8) + 2900 : x^{2} + 8 x + 2900

x^{2} + 8 x + 2900 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 8 \pm 8 ^{2} - 4 \cdot 1 \cdot 2900}{2 \cdot 1}

Simplify

8^{2} - 4 \cdot 1 \cdot 2900 : 4721 i

x_{1, 2} = \frac{- 8 \pm 4 721 i}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 8 + 4 721 i}{2 \cdot 1}, x_{2} = \frac{- 8 - 4 721 i}{2 \cdot 1}

x = \frac{- 8 + 4 721 i}{2 \cdot 1} : - 4 + 2721 i

x = \frac{- 8 - 4 721 i}{2 \cdot 1} : - 4 - 2721 i

The solutions to the quadratic equation are:

x = - 4 + 2721 i, x = - 4 - 2721 i

12 x^{2} - 54 x = 0

x, y^{3} - 3 y^{2} - 9 y = x^{2} + 6 x - 26

7 - 4 t - 0.5 t^{2} = 0

2 x^{2} + 7 x - 8 = 0

\frac{1 4 ^{2}}{2 0 ^{2}} + \frac{y ^{2}}{1 5 ^{2}} = 1
