Answer:

A) y² - 5y + 1

B) y² - 5y - 4

C) - 5y + 1

D) - 3y² - 4y - 6

Step-by-step explanation:

Let's call P the unkown polynomial and D the difference. In each case, the following must be true:

y² - 5y + 1 - P = D

<em>A)</em>

y² - 5y + 1 - P = 0

y² - 5y + 1 = P

<em>B)</em>

y² - 5y + 1 - P = 5

y² - 5y + 1 - 5 = P

y² - 5y - 4 = P

<em>C)</em>

y² - 5y + 1 - P = y²

y² - 5y + 1 - y² = P

- 5y + 1 = P

<em>D) </em>

y² - 5y + 1 - P = 4y² - y + 7

y² - 5y + 1 - 4y² + y - 7 = P

- 3y² - 4y - 6 = P

Answer:

Subtract each term from the polynomial until you find the matching polynomial.

Step-by-step explanation:

Subtracting each answer option below yields the following polynomials:

A) y^2-5y+1-0= y^2-5y+1

B) y^2-5y+1-5 = y^2-5y-4

C) y^2-5y+1-y^2 = -5y+1

D) y^2-5y+1 - (4y^2-y+7) \\y^2 -5y+1-4y^2+y-7\\-3y^2-4y-6
