Answer:
2y² + 8y + 2 + (y - 10)/(2y^2 -y+2)
Explanation:
(4y^4 + 14y^3 + 15y - 6) : (2y^2 -y+2) =
2y² + 8y + 2
----------------------------------------
2y² - y + 2 | 4y^4 + 14y³ + 0y² + 15y - 6
(-) 4y^4 - 2y³ + 4y²
16y³ - 4y² + 15y
(-) 16y³ - 8y² + 16y
4y² - y - 6
(-) 4y² - 2y + 4
y - 10
(4y^4 + 14y^3 + 15y - 6) : (2y^2 -y+2) = 2y² + 8y + 2 + (y - 10)/(2y^2 -y+2)
