Step-by-step explanation:
Terms are the numbers and/or variables within an equation. For example you have 5 terms in that equation:
[tex]3x^2+7y^3+2x+9y-5y^2[/tex]
The first term is: [tex]3x^2[/tex]
The second term is: [tex]7y^3[/tex]
The third term is: [tex]2x[/tex]
The fourth term is: [tex]9y[/tex]
The fifth term is: [tex]-5y^2[/tex]
Coefficients are the numbers in front of variables (this includes negative/subtraction signs). For example you have 5 coefficients in this equation:
The first coefficient is: 3
The second coefficient is: 7
The third coefficient is: 2
The fourth coefficient is: 9
The fifth coefficient is: -5
