Debras fish tank 16 liters which mean she have 80 liter
We will subtract 2y^2-3y-5 from y^3-6y^2+5y
This is written as follows:
y^3-6y^2+5y - (2y^2-3y-5)
note that the subtraction means that some signs would change as follows:
y^3-6y^2+5y - 2y^2+3y+5
Now we will subtract the coefficients of like terms as follows:
y^3 - y^2(6+2) + y(5+3) + 5
= y^3 - 8y^2 + 8y + 5
