6770 = 62 x^{2} + 60 x - 30

x = 10, x = - \frac{340}{31}

Decimal Notation

x = 10, x = - 10.96774 \dots

Solution steps

6770 = 62 x^{2} + 60 x - 30

Switch sides

62 x^{2} + 60 x - 30 = 6770

Move

6770

to the left side

62 x^{2} + 60 x - 6800 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 60 \pm 6 0 ^{2} - 4 \cdot 62 ( - 6800 )}{2 \cdot 62}

6 0^{2} - 4 \cdot 62 (- 6800) = 1300

x_{1, 2} = \frac{- 60 \pm 1300}{2 \cdot 62}

Separate the solutions

x_{1} = \frac{- 60 + 1300}{2 \cdot 62}, x_{2} = \frac{- 60 - 1300}{2 \cdot 62}

x = \frac{- 60 + 1300}{2 \cdot 62} : 10

x = \frac{- 60 - 1300}{2 \cdot 62} : - \frac{340}{31}

The solutions to the quadratic equation are:

x = 10, x = - \frac{340}{31}

2 x^{2} + 14 x + 20 = 216

5 x^{2} - 14 x + 9 = 0

x, y^{3} + y x^{2} + x^{2} - 3 y^{2} = 0

x, x^{2} y + 2 x y - x - 3 y + 3 = 0

x^{2} - 4 x - 60 = 0
