Question

Which of the following expressions are polynomials? Which are not? Give reasons y square-8​

Answer 1

Step-by-step explanation:

(c) 2 x+x3+3x2 is a mathematical expression consisting of a sum of terms, each term including a variable or variables raised to a power and multiplied by a coefficient. Also, the exponent of the variable x is a whole number. Therefore, 2 x+x3+3x2 is a polynomial.Jan 17, 2020

The simplest polynomials have one variable. ... Now, in the expression y5x4+7x2y2−8, it is clear that the variable y is in the denominator which means that the exponent of the variable y will become −1 when it will be expressed as a numerator and we know that −1 is a negative number, so the expression is not a polynomial.
