3 x^{2} + 5 x - 8 = 0

x = 1, x = - \frac{8}{3}

Decimal

x = 1, x = - 2.66666 \dots

Solution steps

3 x^{2} + 5 x - 8 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 5 \pm 5 ^{2} - 4 \cdot 3 ( - 8 )}{2 \cdot 3}

5^{2} - 4 \cdot 3 (- 8) = 11

x_{1, 2} = \frac{- 5 \pm 11}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- 5 + 11}{2 \cdot 3}, x_{2} = \frac{- 5 - 11}{2 \cdot 3}

x = \frac{- 5 + 11}{2 \cdot 3} : 1

x = \frac{- 5 - 11}{2 \cdot 3} : - \frac{8}{3}

The solutions to the quadratic equation are:

x = 1, x = - \frac{8}{3}

10 < - x + 13

\frac{a ^{3} + b ^{3}}{a + b}

\frac{3 x ^{- 3} y ^{3}}{9 x ^{4} ( y ^{- 3} ) ^{4}}

∣ x + 1 ∣ < 5

b (a + 1)^{2} - 5 \cdot (a + 1)
