- 1.8 x^{2} + 14.4 x = 0

x = 0, x = 8

Solution steps

- 1.8 x^{2} + 14.4 x = 0

Multiply both sides by

10

- 18 x^{2} + 144 x = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 144 \pm 14 4 ^{2} - 4 ( - 18 ) \cdot 0}{2 ( - 18 )}

14 4^{2} - 4 (- 18) \cdot 0 = 144

x_{1, 2} = \frac{- 144 \pm 144}{2 ( - 18 )}

Separate the solutions

x_{1} = \frac{- 144 + 144}{2 ( - 18 )}, x_{2} = \frac{- 144 - 144}{2 ( - 18 )}

x = \frac{- 144 + 144}{2 ( - 18 )} : 0

x = \frac{- 144 - 144}{2 ( - 18 )} : 8

The solutions to the quadratic equation are:

x = 0, x = 8

∣ x ∣ - 5 \leq - 2

(x + 9)^{2} (x + 2) (x - 1) > 0

\frac{150}{5 ^{4}} - \frac{10}{5 ^{3}}

(x + 1) (x + 5) > 0

11 x = 121
