7 x^{2} + 9 x = 0

x = 0, x = - \frac{9}{7}

Decimal Notation

x = 0, x = - 1.28571 \dots

Solution steps

7 x^{2} + 9 x = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 9 \pm 9 ^{2} - 4 \cdot 7 \cdot 0}{2 \cdot 7}

9^{2} - 4 \cdot 7 \cdot 0 = 9

x_{1, 2} = \frac{- 9 \pm 9}{2 \cdot 7}

Separate the solutions

x_{1} = \frac{- 9 + 9}{2 \cdot 7}, x_{2} = \frac{- 9 - 9}{2 \cdot 7}

x = \frac{- 9 + 9}{2 \cdot 7} : 0

x = \frac{- 9 - 9}{2 \cdot 7} : - \frac{9}{7}

The solutions to the quadratic equation are:

x = 0, x = - \frac{9}{7}

1 - 0.5 x - 0.05 x^{2} = 0

15 = \frac{5}{3} (x + 12) 35 (x + 12)

L (q) = - 4 q^{2} + 1 q - 12

4 x^{2} - 80 x + 139 = - 5

q^{2} + 5 q - 36 = 0
