3 x^{2} + 18 x + 20 = 0

x = \frac{- 9 + 21}{3}, x = - \frac{9 + 21}{3}

Decimal Notation

x = - 1.47247 \dots, x = - 4.52752 \dots

Solution steps

3 x^{2} + 18 x + 20 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 18 \pm 1 8 ^{2} - 4 \cdot 3 \cdot 20}{2 \cdot 3}

1 8^{2} - 4 \cdot 3 \cdot 20 = 221

x_{1, 2} = \frac{- 18 \pm 2 21}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- 18 + 2 21}{2 \cdot 3}, x_{2} = \frac{- 18 - 2 21}{2 \cdot 3}

x = \frac{- 18 + 2 21}{2 \cdot 3} : \frac{- 9 + 21}{3}

x = \frac{- 18 - 2 21}{2 \cdot 3} : - \frac{9 + 21}{3}

The solutions to the quadratic equation are:

x = \frac{- 9 + 21}{3}, x = - \frac{9 + 21}{3}

81 x^{2} - 108 x + 36 = 0

a^{2} + 3 5^{2} = 3 7^{2}

3 x^{2} - 32 x + 13 = - 10 x + 6

2 x^{2} - 3 x - 2 = 0

15 x^{2} + 13 x - 20 = 0
