Answer:
Explanation:
algebraic expressions that are written with variables and exponents are called polynomial expressions for example,
x² + 2x - 2
(2a - b)²
5x² + 2y - 7
etc etc
the expressions with negative exponents and the expressions which have a variable in their denominator are non polynomial expressions. for example,
x⁻² + 5
2 / (x+3)
