- 3 x^{2} + 21 x = 0

x = 0, x = 7

Solution steps

- 3 x^{2} + 21 x = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 21 \pm 2 1 ^{2} - 4 ( - 3 ) \cdot 0}{2 ( - 3 )}

2 1^{2} - 4 (- 3) \cdot 0 = 21

x_{1, 2} = \frac{- 21 \pm 21}{2 ( - 3 )}

Separate the solutions

x_{1} = \frac{- 21 + 21}{2 ( - 3 )}, x_{2} = \frac{- 21 - 21}{2 ( - 3 )}

x = \frac{- 21 + 21}{2 ( - 3 )} : 0

x = \frac{- 21 - 21}{2 ( - 3 )} : 7

The solutions to the quadratic equation are:

x = 0, x = 7

0 = x^{2} - 9 x + 8

y, 6 y^{2} d = 12

x, 8 x^{2} - k x + 2 = 0

4 x^{2} - 17 x + 3 = 0

2 x^{2} + 2 x = 0
