3x2
5a²b4
2x2 + 3x - 8
Type of Polynomial


Coefficient


Constant
​

Answer 1

Answer with explanation:

• An algebraic expression having one term is known as a monomial.
• An algebraic expression having two terms is known as binomial.
• An algebraic expression having three terms is known as trinomial.

• Numerical coefficient - Number written before variable in each term.
• Constant - term with no variable ( only number).

Let's check the given expressions :

`3x^2`

Type - Monomial ( having one term)

Coefficient of
`x^2`= 3

Constant =0

`5a^2b^4`

Type - Monomial ( having one term)

Coefficient of
`a^2b^4`= 5

Constant =0

`2x^2 + 3x - 8`

Type - trinomial ( having 3 terms)

Coefficient of
`x^2` = 2

Coefficient of
`x=3`

Constant = -8
