good morning Kingsley: The question is asking you to find the value of x that makes the equation equal to zero. This is the same thing as asking where does the graph cross the xaxis.
Since you have to parts (two things in parenthesis) set each equal to zero:
x^2 3 = 0 and solve for x. Remember when you take the square root of 3 you will have a positive and a negative answer!
x^2 +3 4 = 0 and solve for x by factoring into two parts (x+4)(x3) and set each of these equal to zero.
Does that make sense?
You will have four answers or four places the graph crosses the xaxis.
