Check the picture below.
recall that in a square, all sides are equal, so if we make b = a, then we get that for one side, also recall that the area of a rectangle is length*width, so in this case,
 
 
        
        
        
Answer:
The answer to your question is below
Step-by-step explanation:
a)                             
Factor the numerator is a polynomial of the form    x² + bx + c
                                               s² - 3s - 28 = (s - 7)( s + 4)
Substitute
                                
Simplify like terms
Result                                               s + 4
b)                          
Factor the numerator is a polynomial of the form x² + bx + c
                                            c² + 5c - 24 = (c + 8)(c - 3) 
Substitute
                                           
Simplify like terms                            c - 3
Result                                                c - 3
