Y2+3y−4divided by y^2−5y+4
step 2 of 2 : determine what value(s), if any, of the variable must be excluded.

98 points

(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)

(y+4)

(y-4)
