Simplify the expression if possible state excluded values

Question

y²+5y+6 over y² -5y+6

Answer 1

Nkeiruka:

 

Factorize numerator and denominator.

 

(y² + 5y + 6) / (y² - 5y + 6) = [((y + 2) (y + 3)] / [( y - 2 )(y - 3)].

 

Remember, never to divide by zero! 

 

SO, exclude y = 2 or  y =3 (inclusive or, that means either y = 2, y = 3 OR both) because those values make the denominator zero.

 

No further simplification seems possible.
