thank you very much
To subtract 7y^2 - 3y from 4y^2 + 2y, you need to combine like terms.
First, let's write the expression 4y^2 + 2y on top and 7y^2 - 3y underneath, like this:
4y^2 + 2y
- (7y^2 - 3y)
Now let's distribute the negative sign to each term in the expression below it:
4y^2 + 2y
- 7y^2 + 3y
Next, you need to combine the like terms by adding or subtracting them. In this case, you have y^2 terms and y terms.
For the y^2 terms, 4y^2 - 7y^2 equals -3y^2.
For the y terms, 2y + 3y equals 5y.
Combine these results:
-3y^2 + 5y
So, the answer to the subtraction 7y^2 - 3y from 4y^2 + 2y is -3y^2 + 5y.
