3 u^{2} + 5 u = - 2

u = - \frac{2}{3}, u = - 1

Decimal Notation

u = - 0.66666 \dots, u = - 1

Solution steps

3 u^{2} + 5 u = - 2

Move

2

to the left side

3 u^{2} + 5 u + 2 = 0

Solve with the quadratic formula

u_{1, 2} = \frac{- 5 \pm 5 ^{2} - 4 \cdot 3 \cdot 2}{2 \cdot 3}

5^{2} - 4 \cdot 3 \cdot 2 = 1

u_{1, 2} = \frac{- 5 \pm 1}{2 \cdot 3}

Separate the solutions

u_{1} = \frac{- 5 + 1}{2 \cdot 3}, u_{2} = \frac{- 5 - 1}{2 \cdot 3}

u = \frac{- 5 + 1}{2 \cdot 3} : - \frac{2}{3}

u = \frac{- 5 - 1}{2 \cdot 3} : - 1

The solutions to the quadratic equation are:

u = - \frac{2}{3}, u = - 1

9 a^{2} b^{3} + 15 a^{5} b^{4}

4 ∣ x - 2 ∣ + 1 = 21

x^{2} + 10 x y + 25 y^{2}

\frac{∣ 3 x + 1 ∣}{∣ x + 3 ∣} < 1

- 1 y = - 69
