It is into its proper fraction and cannot be simplified down any further. Therefore the proper fraction is 1/2
The trick is to exploit the difference of squares formula,

Set a = √8 and b = √6, so that a + b is the expression in the denominator. Multiply by its conjugate a - b:

Whatever you do to the denominator, you have to do to the numerator too. So

Expand the numerator:






So we have

But √12 = √(3•4) = 2√3, so

The odds are Rarely for two people
We just look at where the curve cuts the x axis.
Taking each stroke as 1 unit.
The solution to the graph is, x = -3, or 5.
