What polynomial should be subtracted from the polynomial y2–5y+1 to get the difference equal to: 0 show work

y = 5 or y = 0

Step-by-step explanation:

Solve for y over the real numbers:

y^2 - 5 y = 0

Factor y from the left hand side:

y (y - 5) = 0

Split into two equations:

y - 5 = 0 or y = 0

Add 5 to both sides:

y = 5 or y = 0
