Answer:

y-1/y^2 +4y

Explanation:

2y - 1/y x (y + 4) - y-2/y^2 +4y - 2y -8

2y-1/y x (y+4 - y-2/y x (y +4 ) - 2(y + 4)

2y -1 / y x (y+4) - y-2/(y+4) x (y-2)

2y-1/y x (y+4) - 1/y +4

2y -1 -y/y x (y + 4)

y-1/y^2 +4y

Answer:


(y-1)/(y(y+4))

Explanation:

Given expression:


\implies (2y-1)/(y^2+4y)-(y-2)/(y^2+2y-8)

Factor the denominators of both fractions:


\implies (2y-1)/(y(y+4))-(y-2)/(y^2+4y-2y-8)


\implies (2y-1)/(y(y+4))-(y-2)/(y(y+4)-2(y+4))


\implies (2y-1)/(y(y+4))-(y-2)/((y-2)(y+4))

Cancel the common factor (y - 2) of the right fraction:


\implies (2y-1)/(y(y+4))-(1)/((y+4))

Adjust the fractions based on the LCM of y(y + 4):


\implies (2y-1)/(y(y+4))-(y)/(y(y+4))


\textsf{Apply the fraction rule} \quad (a)/(c)-(b)/(c)=(a-b)/(c):


\implies (2y-1-y)/(y(y+4))

Simplify:


\implies (y-1)/(y(y+4))
