99 a^{2} + 55 a = 0

a = 0, a = - \frac{5}{9}

Decimal Notation

a = 0, a = - 0.55555 \dots

Solution steps

99 a^{2} + 55 a = 0

Solve with the quadratic formula

a_{1, 2} = \frac{- 55 \pm 5 5 ^{2} - 4 \cdot 99 \cdot 0}{2 \cdot 99}

5 5^{2} - 4 \cdot 99 \cdot 0 = 55

a_{1, 2} = \frac{- 55 \pm 55}{2 \cdot 99}

Separate the solutions

a_{1} = \frac{- 55 + 55}{2 \cdot 99}, a_{2} = \frac{- 55 - 55}{2 \cdot 99}

a = \frac{- 55 + 55}{2 \cdot 99} : 0

a = \frac{- 55 - 55}{2 \cdot 99} : - \frac{5}{9}

The solutions to the quadratic equation are:

a = 0, a = - \frac{5}{9}

2 x^{2} - 6 x = 6 \times 2 - 8 x

(x - 3)^{2} = - 25

- 6 x^{2} - 96 x - 90 = 0

2 4^{2} + 1 0^{2} = x^{2}

(x - 3) (x + 6) = 0
