5 x^{2} - 40 x + 50 = 0

x = 4 + 6, x = 4 - 6

Solution steps

5 x^{2} - 40 x + 50 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 40 ) \pm ( - 40 ) ^{2} - 4 \cdot 5 \cdot 50}{2 \cdot 5}

(- 40)^{2} - 4 \cdot 5 \cdot 50 = 106

x_{1, 2} = \frac{- ( - 40 ) \pm 10 6}{2 \cdot 5}

Separate the solutions

x_{1} = \frac{- ( - 40 ) + 10 6}{2 \cdot 5}, x_{2} = \frac{- ( - 40 ) - 10 6}{2 \cdot 5}

x = \frac{- ( - 40 ) + 10 6}{2 \cdot 5} : 4 + 6

x = \frac{- ( - 40 ) - 10 6}{2 \cdot 5} : 4 - 6

The solutions to the quadratic equation are:

x = 4 + 6, x = 4 - 6

x^{2} - 9 x + 7 = 0

7 = x (x - 4)

15 x^{2} - 4 x - 126 = - 30

\frac{k ^{2}}{1.2 - 7} = 23

x^{2} - 4 + 3 = 0
