Quizplus · Accepted Answer

The given inequality $x^2 + 4 > 0$ is always true for all real values of $x$ because $x^2$ is always non-negative and adding 4 to it makes the expression strictly positive for all $x$.

Solve the Inequality x2+4>0x ^ { 2 } + 4 > 0x2+4>0

Solve the Inequality $x ^ { 2 } + 4 > 0$
