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) [tex]y^2-5y+1-0= y^2-5y+1[/tex]
B) [tex]y^2-5y+1-5 = y^2-5y-4[/tex]
C) [tex]y^2-5y+1-y^2 = -5y+1[/tex]
D) [tex]y^2-5y+1 - (4y^2-y+7) \\y^2 -5y+1-4y^2+y-7\\-3y^2-4y-6[/tex]
