sqrt(3-x)-sqrt(x+1)> 1/2

3 - x - x + 1 > \frac{1}{2}

- 1 \leq x < - \frac{31}{8} + 1

Interval Notation

[- 1, - \frac{31}{8} + 1)

Decimal Notation

- 1 \leq x < 0.30402 \dots

Solution steps

3 - x - x + 1 > \frac{1}{2}

Add

x + 1

to both sides

3 - x - x + 1 + x + 1 > \frac{1}{2} + x + 1

Simplify

3 - x > \frac{1}{2} + x + 1

f (x) > g (x)

then

g (x) < 0 or g (x) \geq 0

For

\frac{1}{2} + x + 1 < 0 :

No Solution

For

\frac{1}{2} + x + 1 \geq 0 : x < - \frac{31}{8} + 1
