0 = - 3 x^{2} + 9 x + 30

x = - 2, x = 5

Solution steps

0 = - 3 x^{2} + 9 x + 30

Switch sides

- 3 x^{2} + 9 x + 30 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 9 \pm 9 ^{2} - 4 ( - 3 ) \cdot 30}{2 ( - 3 )}

9^{2} - 4 (- 3) \cdot 30 = 21

x_{1, 2} = \frac{- 9 \pm 21}{2 ( - 3 )}

Separate the solutions

x_{1} = \frac{- 9 + 21}{2 ( - 3 )}, x_{2} = \frac{- 9 - 21}{2 ( - 3 )}

x = \frac{- 9 + 21}{2 ( - 3 )} : - 2

x = \frac{- 9 - 21}{2 ( - 3 )} : 5

The solutions to the quadratic equation are:

x = - 2, x = 5

49 x^{2} + 9 x = 0

x, 13 x^{2} + 23 x y + 15 y^{2} - 48 = 0

0 = - 0.2 q^{2} + 250 q - 75000

x^{2} + 16 x - 63 = 0

3 c^{2} - 3 = 1
