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

4y^2–y+7
please explain

Respuesta :

Good evening

Answer:

-3y² − 4y - 6

Step-by-step explanation:

______________________

y² – 5y + 1 − P = 4y² – y + 7

then

P = y² – 5y + 1 − (4y² – y + 7)

then

P = y² – 5y + 1 − 4y² + y − 7

then

P = (y² – 4y²) − (5y − y) + (1 − 7)

then

P = -3y² − 4y - 6
