An example of a quadratic function with only one root is the function x^2. This is only equal to zero when x is equal to zero. It might also happen that there are no roots. This is, for example, the case for the function x^2+3. Then, to find the root, we have to have an ...
Note that y≠q0 (for otherwise √(x^2+4x+3)= -x-2, and squaring both sides gives x^2+4x+3=x^2+4x+4 which is impossible). We have 1y=1(x+2+√(x^2+4x+3))·(x+2-√(x^2+4x+3))(x+2-√(x^2+4x+3))=x+2-√(x^2+4x+3). Hence the equation in the question...
To find the intersection of two lines, set the expressions as equal and solve for x. Then determine y by filling in the x you found.
