- 3 < x < - 1

+1

Interval Notation

(- 3, - 1)

Solution steps

3 x^{2} + 9 x + 9 < - 3 x

Rewrite in standard form

x^{2} + 4 x + 3 < 0

Factor

x^{2} + 4 x + 3 : (x + 1) (x + 3)

(x + 1) (x + 3) < 0

Identify the intervals

- 3 < x < - 1

- 6 < ∣ x ∣ < 6

join-(5pi)/4+2pi join

- \frac{5 π}{4} + 2 π

∣ 3 x + 3 ∣ = ∣ 7 x + 3 ∣

|(2p-8)/4 |>= 9

\frac{2 p - 8}{4} \geq 9

simplify (1/530*10^{-3})/(540*10^{-9)}simplify

\frac{\frac{1}{530} \cdot 1 0 ^{- 3}}{540 \cdot 1 0 ^{- 9}}
