Like And Unlike Terms, Degree Of Expressions

 

Like terms: The terms having the same literal (variable) with same exponents are called Like terms. 

Example: 

  • 48x and -8x
  • 5x2 and ½ x 2 

Unlike terms: The terms having the same variable with different exponents or different variable with same exponents are called Unlike terms .

Example: 

  • 8x and 3y
  • 6x2and 3y2 

The degree:

The degree is the value of the greatest exponent of any expression. To find the degree we have to find the largest exponent in the polynomial. Coefficients can be ignored when we are finding the degree.

Demonstration:
Determine the degree of the polynomial 4x2 + x + 42?
The value of the largest exponent the answer is 2 since the first term is squared. Remember coefficients have nothing at all do to with the degree.
