x^{2} + 6 x + 3 = 80

x = - 3 + 86, x = - 3 - 86

Decimal Notation

x = 6.27361 \dots, x = - 12.27361 \dots

Solution steps

x^{2} + 6 x + 3 = 80

Move

80

to the left side

x^{2} + 6 x - 77 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 6 \pm 6 ^{2} - 4 \cdot 1 \cdot ( - 77 )}{2 \cdot 1}

6^{2} - 4 \cdot 1 \cdot (- 77) = 286

x_{1, 2} = \frac{- 6 \pm 2 86}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 6 + 2 86}{2 \cdot 1}, x_{2} = \frac{- 6 - 2 86}{2 \cdot 1}

x = \frac{- 6 + 2 86}{2 \cdot 1} : - 3 + 86

x = \frac{- 6 - 2 86}{2 \cdot 1} : - 3 - 86

The solutions to the quadratic equation are:

x = - 3 + 86, x = - 3 - 86

4 x^{2} + 28 x + 49 = 5

10 x^{2} + 10 x = 0

34.04 = 0.9 \cdot 2 \cdot 0.85 \cdot 210 \cdot x \cdot 0.2 (40 - \frac{x}{2})

34 x + x^{2}

2 z^{2} + 11 z + 15 = 0
