Answer 3

To solve the inequality $x^2 + 4 < 0$, we need to find the values of $x$ that satisfy the inequality.

However, the expression $x^2 + 4$ can never be less than zero because the square of any real number is always non-negative (greater than or equal to zero). Therefore, there are no real values of $x$ that satisfy the inequality $x^2 + 4 < 0$.

To further illustrate this, let's prove that $x^2 + 4 \geq 0$ for all real values of $x$:

For any real number $x$, we know that $x^2 \geq 0$ (the square of any real number is non-negative). Additionally, $4$ is also greater than or equal to $0$. So, the sum of two non-negative numbers will also be non-negative:

$x^2 \geq 0 \quad \text{and} \quad 4 \geq 0 \implies x^2 + 4 \geq 0.$

Therefore, there are no real solutions to the inequality $x^2 + 4 < 0$.
