What to Focus On

  • Terms, variables, coefficients, and constants must be identified correctly.
  • A polynomial has only one variable in this chapter.
  • Degree means the highest power of the variable.

  • A linear polynomial is not the same as a linear equation.
  • An equation appears only after equating the polynomial to a constant.
  • The solution of Example 6 is 27 and 37.

  • Substitute the given value of the variable carefully.
  • 2x + 3 gives output 11 when x = 4.
  • 2x + 3 gives output -9 when x = -6.

Common Mistakes to Avoid

Any algebraic expression with letters is a polynomial, even if it has more than one variable.

A linear polynomial is the same as a linear equation.

The constant 8 is not a polynomial because it has no variable.

Memory Tips
