-5x^2+20x=0

Solution

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

Solution

x = 0, x = 4

Solution steps

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

Solve with the quadratic formula

x_{1, 2} = \frac{- 20 \pm 2 0 ^{2} - 4 ( - 5 ) \cdot 0}{2 ( - 5 )}

2 0^{2} - 4 (- 5) \cdot 0 = 20

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

Separate the solutions

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

x = \frac{- 20 + 20}{2 ( - 5 )} : 0

x = \frac{- 20 - 20}{2 ( - 5 )} : 4

The solutions to the quadratic equation are:

x = 0, x = 4
