please ans quickly because I need ans in 5 min​

Answer 1

We know that each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable or variables. Each term in an algebraic expression is separated by a positive sign or a negative sign.

For example, in the expression 4x

2

y

2

−4x

2

y

2

z

2

+z

2

, the terms are: 4x

2

y

2

,−4x

2

y

2

z

2

and z

2

.

Also, when a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.

For example, in the expression 4x

2

y

2

−4x

2

y

2

z

2

+z

2

, the coefficients are: 4,−4 and 1.

Hence, the terms are 4x

2

y

2

,−4x

2

y

2

z

2

,z

2

and the coefficients are 4,−4,1
