x^{2} - 18 x + 70 = 0

x = 9 + 11, x = 9 - 11

Solution steps

x^{2} - 18 x + 70 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 18 ) \pm ( - 18 ) ^{2} - 4 \cdot 1 \cdot 70}{2 \cdot 1}

(- 18)^{2} - 4 \cdot 1 \cdot 70 = 211

x_{1, 2} = \frac{- ( - 18 ) \pm 2 11}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 18 ) + 2 11}{2 \cdot 1}, x_{2} = \frac{- ( - 18 ) - 2 11}{2 \cdot 1}

x = \frac{- ( - 18 ) + 2 11}{2 \cdot 1} : 9 + 11

x = \frac{- ( - 18 ) - 2 11}{2 \cdot 1} : 9 - 11

The solutions to the quadratic equation are:

x = 9 + 11, x = 9 - 11

c - 32 \geq 0

\frac{x - 12}{x} \leq \frac{20}{1 - x}

2 x^{2} + 7 x = - 3

3 x^{2} - 12 x + 6 = 0

∣ x + 2 ∣ + ∣ x ∣ \leq 3
