Question 117276: Please help me to solve and under stand rational expressions.
The questions states for all r not equal to +2 or -2,
r^2 - 5r +6 / r^2 - 4 = ?

You can put this solution on YOUR website!
r^2 - 5r +6 / r^2 - 4 = ?
Factor to get:
[(r-3)(r-2)]/[(r-2)(r+2)]
Cancel the common (r-2) to get:
= (r-3)/(r+2)
