You can put this solution on YOUR website! x^2+8x+6/x^2-16; the denominator is the difference of squares
but the numerator can't be factored.
The expression is in its simplest form.
If it is an equation, equaling 0,
then the roots are x=(1/2)(-8 +/- sqrt (64-24)); sqrt 40= 2 sqrt (10)
x=-4+/-sqrt (10)
Numerically, this is -7.16 and -0.84 for the roots, with a vertical asymptote at x=4
