Q

What is a coefficient and a variable

A

Coefficient is the number

Variable consist of more than one letter or symbol

17
Q

What is a constant

A

A term with no variable

18
Q

What is monomial

A

Type of polynomial

Has 1 number of term

Ex: x, 3y, -4z, 5

19
Q

What is a binomial

A

Type of polynomial

Has 2 number of terms

Ex: 2x-3, ab + 2a, 0.5x - x

20
Q

What is a trinomial

A

Type of polynomial

Has 3 number of terms

Ex: 2x+3x-1

21
Q

What are types of polynomials

A

Monomial

Binomial

Trinomial

22
Q

What is the degree of a term

A

The sum of the exponents on the variables in a term

Ex:

4x to the power of 2 y to the power of three (2+3=5) would be a degree of 5

Xsquared would be degree of 2

-5 would be degree of 0

23
Q

What is a degree of a polynomial

A

The degree of the highest degree term

Ex: -2A to the power of 2 (degree of 2) + a to the power of 3 B to the power of 3 (degree of 5)

So the polynomial is degree 5

24
Q

What are like terms

A

Have identical variables and exponents

Ex:
3x+5+2x+1
In like terms is 3x+2x +5+ 1
=5x+6

25
