Subtraction of Unlike Terms

The subtraction of unlike terms cannot be subtracted. For example, a - b will remain same as it is. Suppose the difference between two like terms is a single like term; but the two unlike terms cannot be subtracted to get a single term.


Subtraction of two positive unlike terms:

To find the difference of two positive unlike terms suppose, take n from m, we need to connect both the terms by using a subtraction sign and express the result in the form of m - n.

Therefore, the difference of two positive unlike terms m and n = m - n.


Subtraction of positive and negative unlike terms:

To find the difference of a positive and a negative unlike terms suppose, take -n from m, we need to connect both the terms by using a subtraction sign [m - (-n)] and express the result in the form of m + n.

Therefore, the difference of a positive and a negative unlike terms m and -n = m + n.

Subtraction of negative and positive unlike terms:

To find the difference of a negative and a positive unlike terms suppose, take n from -m, we need to connect both the terms by using a subtraction sign [(-m) - n] and express the result in the form of -m - n.

Therefore, the difference of a negative and a positive unlike terms -m and n = -m - n.


Subtraction of negative and negative unlike terms:

To find the difference of two negative unlike terms suppose, take -n from -m, we need to connect both the terms by using a subtraction sign [(-m) - (-n)] and express the result in the form of -m + n.

Therefore, the difference of two negative unlike terms -m and -n = -m + n.


For example:

1. The unlike terms 2ab and 4bc cannot be subtracted to form a single term. All that which can be done is to connect them by the sign of subtraction and leave the result in the form 2ab - 4bc.


2. 11x - 7y -2x - 3x.

= 11x - 2x - 3x - 7y.

= 6x - 7y (here 7y is an unlike term)


3. 3x - 7y

Here 3x and 7y both are unlike terms so it will remain as it is.

Therefore, the answer is 3x - 7y


4. 15x - 12y - 11x

= 15x - 11x - 12y

= 4x - 12y (here 12y is an unlike term)
