4y^2-10y-1

Step-by-step explanation:

Given : (y^2-7y-5)-(-3y^2+3y-4)

To Find:Subtract and simplify the given expression.

Solution:

(y^2-7y-5)-(-3y^2+3y-4)

y^2-7y-5+3y^2-3y+4

y^2+3y^2-7y-3y-5+4

Solving the like terms

4y^2-10y-1

Thus the simplified expression is 4y^2-10y-1

Hence After subtracting and simplifying the expression (y^2-7y-5)-(-3y^2+3y-4) we get 4y^2-10y-1
