x^{2} - 20 x = - 75

x = 15, x = 5

Solution steps

x^{2} - 20 x = - 75

Move

75

to the left side

x^{2} - 20 x + 75 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 20 ) \pm ( - 20 ) ^{2} - 4 \cdot 1 \cdot 75}{2 \cdot 1}

(- 20)^{2} - 4 \cdot 1 \cdot 75 = 10

x_{1, 2} = \frac{- ( - 20 ) \pm 10}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 20 ) + 10}{2 \cdot 1}, x_{2} = \frac{- ( - 20 ) - 10}{2 \cdot 1}

x = \frac{- ( - 20 ) + 10}{2 \cdot 1} : 15

x = \frac{- ( - 20 ) - 10}{2 \cdot 1} : 5

The solutions to the quadratic equation are:

x = 15, x = 5

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

36 k^{2} = 25

2 x^{2} - 4 x + 3 = 0

y^{2} - 6 y + 3 = 0

y = 2.49 \cdot 1 0^{- 3} (1 - \frac{0.5714 - 2000 y}{- 2})^{2}
