What polynomial should be subtracted from the polynomial y^2–5y+1 to get the difference equal to: 5 ^=power

y^2 - 5y - 4

Step-by-step explanation:

So you want f(y) such that

(y^2-5y+1) - f(y) = 5

Subtract both sides by (y^2-5y+1):

-f(y) = 5 - (y^2-5y+1)

-f(y) = -y^2 + 5y + 4

f(y) = y^2 - 5y - 4

So the polynomial you are looking for is y^2 - 5y - 4

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
