Question

1. Which of the following algebraic expressions are not polynomials?

7X^2–5X+11
3Y^3–2Y+√7
Y+ 2/Y
X^2+3XY–9

Answer 1

None are polynomials.

Step-by-step explanation:

For any algebraic expression to be a polynomial it forst has to be an equation. and none of these contains and '=' sign so, none of them are equations.

Hence, none are polynomials.

Answer 2

The algebraic expression y + 2/y is not a polynomial.

• The polynomials are those which does not have negative or fractional powers of variables.
• In 7x²-5x+11, the variable x has powers in the whole number, so it is a polynomial.
• In 3y³-2y+√7, the variable y has powers in the whole number, so it is a polynomial.
• In y + 2/y, the varibale y has negative power, so it is not a polynomial.
• In x² + 3xy -9, the variable x and y have power in the whole number, so it is also a polynomial.

Hence, y + 2/y is not a polynomial.
