5 x^{2} + 7 x - 1 = 0

x = \frac{- 7 + 69}{10}, x = \frac{- 7 - 69}{10}

Solution steps

5 x^{2} + 7 x - 1 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 7 \pm 7 ^{2} - 4 \cdot 5 ( - 1 )}{2 \cdot 5}

7^{2} - 4 \cdot 5 (- 1) = 69

x_{1, 2} = \frac{- 7 \pm 69}{2 \cdot 5}

Separate the solutions

x_{1} = \frac{- 7 + 69}{2 \cdot 5}, x_{2} = \frac{- 7 - 69}{2 \cdot 5}

x = \frac{- 7 + 69}{2 \cdot 5} : \frac{- 7 + 69}{10}

x = \frac{- 7 - 69}{2 \cdot 5} : \frac{- 7 - 69}{10}

The solutions to the quadratic equation are:

x = \frac{- 7 + 69}{10}, x = \frac{- 7 - 69}{10}

x^{2} - 8 x + 10 = 0

7 x^{2} + 6 = 0

5 x + 7 = 12

∣ 2 x - 5 ∣ \leq 9
