Y2+3y−4divided by y^2−5y+4

Mathematics
1 answer:
EleoNora [17]4 years ago
3 0

Answer:

(y+4)

----------------

(y-4)


y cannot equal 4 or 1

Step-by-step explanation:

y^2 +3y -4

-----------------

y^2 -5y +4

I will factor the numerator and the denominator

(y+4) (y-1)

----------------

(y-4) (y-1)

The factors that must be excluded must be determined before we cancel

y cannot equal 4 or 1 because that would make the denominator go to zero

Cancel y-1 from the numerator and denominator

(y+4)

----------------

(y-4)
