sqrt(x^2+3x)<1-x

x^{2} + 3 x < 1 - x

x \leq - 3 or 0 \leq x < \frac{1}{5}

Solution steps

x^{2} + 3 x < 1 - x

f (x) < g (x)

then

g (x) > 0

1 - x > 0 : x < 1

x^{2} + 3 x < 1 - x : x < \frac{1}{5}

Find singularity points

Find non-negative values for radicals:

x \leq - 3 or x \geq 0

Combine the intervals

x < 1 and x < \frac{1}{5} and (x \leq - 3 or x \geq 0)

Verify Solutions:

x \leq - 3

True

, 0 \leq x < \frac{1}{5}

True

The solution is

x \leq - 3 or 0 \leq x < \frac{1}{5}

- (\frac{4}{3})^{3}

5 x^{2} y - 20 y

\frac{2}{5}

12 \cdot x = 48

\frac{5}{12} - \frac{5}{12} x + x = \frac{1}{2}
