Subtract 11 - 15y² from y³ - 15y² - y - 11

Solution:

Given, the expressions are 11 - 15y² and y³ - 15y² - y - 11.

We have to subtract the expressions

On subtracting the expressions,

= y³ - 15y² - y - 11 - (11 - 15y²)

= y³ - 15y² - y - 11 - 11 + 15y²

By combining the like terms,

= y³ - 15y² + 15y² - y - 11 - 11

By distributive property,

= y³ + (-15 + 15)y² - y + (-11 - 11)

= y³ + (0)y² - y + (-22)

= y³ - y - 22

Therefore, the required expression is y³ - y - 22.
