Answer:
The "3y" in the first term is a factor 
The "9" in the second term is a coefficient
The "(7 + 2x)" in the first term is a factor 
Step-by-step explanation:
Given in the question an expression
3y(7 + 2x) + 9xy - 10
- The coefficients are the numbers that multiply the variables, x and y.
<h3>Example</h3>
 6y 
 6 is coefficient
     2.Constants are terms without variables
<h3>Example</h3>
  10
     3.The factors in a mathematical expression are parts of the expression that are connected with multiplication.
<h3> Example</h3>
 (4x+1)(3x+7)
 (4x+1) and (3x+7) both are factors
 
        
             
        
        
        
So first work in the parenthesis my guy
