AysviL [449]

Step-by-step explanation:

A term is a number, a variable, or a constant multiplied by a variable or variables.

Like terms are terms that contain the same variables raised to the same power. Only the numerical coefficients are different.

A coefficient is a multiplicative factor in some term of a polynomial (expression).

Constant is a term in the algebraic expression that contain only number.

n + 5n = n + 5n + 0

terms: n, 5n

like terms: n, 5n

coefficients: 1, 5

constant: 0

simplified form: n + 5n = 6n

term: 6n

coefficient: 6

constant: 0

=======================

12c - c = 12c - c + 0

terms: 12c, -c

like terms: 12c, -c

coefficients: 12, -1

constant: 0

simplified form: 12c - c = 11c

term: 11c

coefficient: 11

constant: 0

========================

-4j - 1 - 4j + 6

terms: -4j, -1, -4j, 6

like terms: -4j, -4j and -1, 6

coefficients: -4, -4

constants: -1, 6

simplified form: -4j - 1 - 4j + 6 = (-4j - 4j) + (-1 + 6) = -8j + 5

term: -8j, 5

coefficient: -8

constant: 5
