Answer:
All the expressions are polynomials
Step-by-step explanation: To identify the below algebraic expression, we should start by a definition of polynomials
Polynomial is an algebraic expression wich consist of various term
according to the number of terms Polynomials are name
bynomial if it is of two terms
trynomial if it is of three terms
Monomial is not a polynomial, since that expression only has one term
Now the main question is?? What is term
Term is a block, or set of letters , numbers and simbols ( such as √ ,² etc) separated with + or - sign, from others in an algebraic expression
For instance
ax² + bx + c is a trynomial
three terms ax² bx and c
- 12x³ √2zb - 4 + 2x as you can see has three terms
Now let have a look at the question
π*x - √3 + 5y is a trynomial
π*x - √3 + 5y +x²y² - 4x³ +12y is a polynomial
4/x - x² - 16 is a trynomial
3.9x³ - 4.1x² + 7.3 is a trynomial
