5 x^{2} + 30 x + 15 = 0

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

Decimal Notation

x = - 0.55051 \dots, x = - 5.44948 \dots

Solution steps

5 x^{2} + 30 x + 15 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 30 \pm 3 0 ^{2} - 4 \cdot 5 \cdot 15}{2 \cdot 5}

3 0^{2} - 4 \cdot 5 \cdot 15 = 106

x_{1, 2} = \frac{- 30 \pm 10 6}{2 \cdot 5}

Separate the solutions

x_{1} = \frac{- 30 + 10 6}{2 \cdot 5}, x_{2} = \frac{- 30 - 10 6}{2 \cdot 5}

x = \frac{- 30 + 10 6}{2 \cdot 5} : - 3 + 6

x = \frac{- 30 - 10 6}{2 \cdot 5} : - 3 - 6

The solutions to the quadratic equation are:

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

y, 5 x^{3} - x y^{2} + 3 y = c

5 x^{2} - 8 x + 13 = 0

7 (x - 1) (x + 1) = 0

x^{2} - 5 x + 6 = 2

x^{2} - 5 x + 6 = 6
