I have a relatively straightforward inequality to solve but I am getting stuck because I don't know what to do with the unknown...
$$x^2 + b^2 > 0, b > 0$$
The aim is to solve the inequality for all values of x. I can't factorise the expression so I wasn't able to draw a sketch of intercepts to help me.
Some pointers in the right direction would be great.
As you are adding two squares they are always positive or equal to zero. As $b>0$ the inequality is strictly positive for all $x \in R$.
