Question 828348
Algebra is easy, all you need to do is concentrate. :)

I will teach you how to identify the terms of expression.

Let's say in,

{{{4x^2}}}
4 here is called the coefficient, x is the variable and 2 is the power. 

7 is simply a constant.


The difference of equation to expression is they have an equal sign.

Equation: x+3=1
Expression: x+3

To identify the terms,

in -4-3x+2xy

-4 is 0 because {{{-4x^0}}} is -4
-3x is 1 because {{{-3x^1}}} is -3x
2xy = 2 because {{{2*x^1*y^1}}}


Hope that helps! :)
