What is the simplified form of the following expression? 4x2 + 3xy−2y+xy−x2

To simplify the expression 4x^2 + 3xy - 2y + xy - x^2, we can combine like terms.

Combining the terms involving x^2, we have (4x^2 - x^2) which simplifies to 3x^2.

Combining the terms involving xy, we have (3xy + xy) which simplifies to 4xy.

Finally, combining the terms involving y, we have (-2y) remaining.

Therefore, the simplified form of the expression is 3x^2 + 4xy - 2y.

To simplify the expression 4x^2 + 3xy - 2y + xy - x^2, you can combine like terms.

Like terms refer to terms that have the same variables raised to the same exponent. In this case, the like terms are the terms with x^2 and the terms with xy.

The simplified form of the expression is obtained by adding or subtracting the coefficients of the like terms while keeping the variables unchanged.

First, let's combine the terms with x^2:
4x^2 - x^2 = 3x^2

Next, let's combine the terms with xy:
3xy + xy = 4xy

Finally, let's bring down the other terms:
4xy - 2y

Putting it all together, the simplified form of the expression 4x^2 + 3xy - 2y + xy - x^2 is 3x^2 + 4xy - 2y.

To which subset of real numbers does the following number belong: 65−−√

To simplify the expression 4x^2 + 3xy - 2y + xy - x^2, we can combine like terms.

First, let's look at the terms with x^2. We have 4x^2 - x^2, which simplifies to 3x^2.

Next, let's look at the terms with xy. We have 3xy + xy, which simplifies to 4xy.

Finally, we have -2y. Since there are no other terms with y, -2y is already in its simplest form.

Combining everything together, our simplified expression is:

3x^2 + 4xy - 2y
