Question

Subtract and simplify. (y2−7y−5)−(−3y2+3y−4)

Answer 1

y2 - 7y -5 +3y2 - 3y +4
=4y2 - 10y - 1

Answer 2

`4y^2-10y-1`

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`
