8 = 3 x^{2} + 2 x

x = \frac{4}{3}, x = - 2

Decimal Notation

x = 1.33333 \dots, x = - 2

Solution steps

8 = 3 x^{2} + 2 x

Switch sides

3 x^{2} + 2 x = 8

Move

8

to the left side

3 x^{2} + 2 x - 8 = 0

Solve with the quadratic formula

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

2^{2} - 4 \cdot 3 (- 8) = 10

x_{1, 2} = \frac{- 2 \pm 10}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- 2 + 10}{2 \cdot 3}, x_{2} = \frac{- 2 - 10}{2 \cdot 3}

x = \frac{- 2 + 10}{2 \cdot 3} : \frac{4}{3}

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

The solutions to the quadratic equation are:

x = \frac{4}{3}, x = - 2

- 3 x^{2} + 16 = - 11

y, u = x^{3} + 3 x y^{2}

2 x^{2} + 12 x + 2 = 0

(x - 1)^{2} + (x + 4)^{2} = 5

x^{2} = 12 x - 36
