Question

Expression

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
