Hi everyone

Q1. When a polynomial P(x) is divided by x^2-5 the remainder is x+4. Find the remainder when P(x)+P(-x) is divided by x^2-5

Q2. Consider the equations of the straight line and the square root,

y=2+ax and y=\sqrt{ 5+x}

Find the set of values of a, when the line intersects the graph of the square root at two distinct points. (For this question, I want to know the algebraical approach. I know that graphical method is much more quicker and easier, however I want to get to know other different ways of approaching. What are the set conditions? Thanks in advance )
