Answer:

2x^{2} - y^{2} +5xy - 2y

A) 4 terms

B) 0 negatives

Step-by-step explanation:

Combine the like terms

So -3x squared + 5x squared = 2x squared

2y squared - 3y squared = -1y squared

There is only one term with 5xy so you leave it as it is

There is only one term with 2y so you leave it as it is

Now put this in an equation and use the negative and positive signs as addition or subtraction signs.

So it looks like:

2x^{2} - y^{2} +5xy - 2y

Answer:

1. 0.5

2. 3/4

3. -6

4. 5x

Step-by-step explanation:

1. A coefficient is a number that is placed in front of an algebraic term/variable in an expression or equation.

The decimal coefficient is therefore 0.5. It is the coefficient of x.

2. The fractional coefficient is 3/4. It is the coefficient of y.

3. The negative coefficient is -6. It is the coefficient of b.

4. A like term is one which contains the same type of terms as another term.

3x is a like term of 5x, because it contains a numerical term and an algebraic term to the power of 1.
