Answer:
The answer is - 2 < x < 2
Step-by-step explanation:
–5 < 2x – 1 < 3
Add 1 to both sides to eliminate - 1
That's
- 5 + 1 < 2x - 1 + 1 < 3+ 1
- 4 < 2x < 4
Divide both sides by 2
That's
- 4/2 < 2x/2 < 4/2
The final answer is
<h3 /><h3>- 2 < x < 2</h3>

Strictly speaking, x^2 + 2x + 4 doesn't have solutions; if you want solutions, you must equate <span>x^2 + 2x + 4 to zero:
</span>x^2 + 2x + 4= 0. "Completing the square" seems to be the easiest way to go here:
rewrite x^2 + 2x + 4 as x^2 + 2x + 1^2 - 1^2 = -4, or
(x+1)^2 = -3
or x+1 =i*(plus or minus sqrt(3))
or x = -1 plus or minus i*sqrt(3)
This problem, like any other quadratic equation, has two roots. Note that the fourth possible answer constitutes one part of the two part solution found above.
