4 x^{2} + 26 x + 30 = 0

x = - \frac{3}{2}, x = - 5

Decimal Notation

x = - 1.5, x = - 5

Solution steps

4 x^{2} + 26 x + 30 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 26 \pm 2 6 ^{2} - 4 \cdot 4 \cdot 30}{2 \cdot 4}

2 6^{2} - 4 \cdot 4 \cdot 30 = 14

x_{1, 2} = \frac{- 26 \pm 14}{2 \cdot 4}

Separate the solutions

x_{1} = \frac{- 26 + 14}{2 \cdot 4}, x_{2} = \frac{- 26 - 14}{2 \cdot 4}

x = \frac{- 26 + 14}{2 \cdot 4} : - \frac{3}{2}

x = \frac{- 26 - 14}{2 \cdot 4} : - 5

The solutions to the quadratic equation are:

x = - \frac{3}{2}, x = - 5

- 5 x^{2} + 10 = 0

15 x^{2} = 540

9 x^{2} + 18 x - 17 = 0

\frac{17}{10} x^{2} + 3 x + 5 = 0

6 w^{2} - 12 w = 0
