Question

Write 5 multinomials
. Every multinomial is a polynomial.​

Answer 1

a + ab + b2 + bc + cd is a multinomial of five terms in four variables a, b, c and d. 5x8 + 3x7 + 2x6 + 5x5 - 2x4 - x3 + 7x2 - x is a multinomial of eight terms in one variable x. These are the types of algebraic expressions explained with various types of examples.

Answer 2

Answer:

Explanation:

What is the difference between "Polynomial" and "Multinomial" in two or more variables?

Since, by definition:

Multinomial:

An algebraic expression having two or more (unlike) terms is called a Multinomial.

For example:

5x2−2x is a multinomial having 2 terms,

5x3−2xy+7y2 is a multinomial having 3 terms,

7xy−9yz+6zx−7 is a multinomial having 4 terms.

Polynomials in two or more variables:

An algebraic expression in two or more variables is called a Polynomial if the Power of every variable in each term is a whole number.

Some books say "Multinomial" is one of the types of "Polynomial", and the other discuss it in particular.

Is the function f cross "Polynomial" or "Multinomial"? Why?

f(x,y)=xy+y2+2xy2+y3−3xy3+xy4,
