5 x^{2} - 20 x + 14 = 0

x = \frac{10 + 30}{5}, x = \frac{10 - 30}{5}

Decimal Notation

x = 3.09544 \dots, x = 0.90455 \dots

Solution steps

5 x^{2} - 20 x + 14 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 20 ) \pm ( - 20 ) ^{2} - 4 \cdot 5 \cdot 14}{2 \cdot 5}

(- 20)^{2} - 4 \cdot 5 \cdot 14 = 230

x_{1, 2} = \frac{- ( - 20 ) \pm 2 30}{2 \cdot 5}

Separate the solutions

x_{1} = \frac{- ( - 20 ) + 2 30}{2 \cdot 5}, x_{2} = \frac{- ( - 20 ) - 2 30}{2 \cdot 5}

x = \frac{- ( - 20 ) + 2 30}{2 \cdot 5} : \frac{10 + 30}{5}

x = \frac{- ( - 20 ) - 2 30}{2 \cdot 5} : \frac{10 - 30}{5}

The solutions to the quadratic equation are:

x = \frac{10 + 30}{5}, x = \frac{10 - 30}{5}

75 x^{2} y^{3} + 60 x y^{3}

8 x - 2 x + 4 = 2 x

z^{2} - 3 z - 54 = 0

3 x - 1 \geq 9 + x

∣ 4 y - 1 ∣ \geq 8
