- 5 x^{2} + 20 x + 60 = 0

x = - 2, x = 6

Solution steps

- 5 x^{2} + 20 x + 60 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 20 \pm 2 0 ^{2} - 4 ( - 5 ) \cdot 60}{2 ( - 5 )}

2 0^{2} - 4 (- 5) \cdot 60 = 40

x_{1, 2} = \frac{- 20 \pm 40}{2 ( - 5 )}

Separate the solutions

x_{1} = \frac{- 20 + 40}{2 ( - 5 )}, x_{2} = \frac{- 20 - 40}{2 ( - 5 )}

x = \frac{- 20 + 40}{2 ( - 5 )} : - 2

x = \frac{- 20 - 40}{2 ( - 5 )} : 6

The solutions to the quadratic equation are:

x = - 2, x = 6

- 9 - 10 a + 7 = - 2

∣ x - 4 ∣ \leq 0

12 x^{2} - 2 x - 2

1 5^{2} + b^{2} = 1 7^{2}

x^{2} - 7 x - 78 = 0
