Step-by-step explanation:
<u>Given</u> 
- f(x) = 4x³ + 3x² - 2x - 1
 
<u>Divide it by the following:</u>
<u>(a) 2x + 1</u>
- 4x³ + 3x² - 2x - 1 =
 - (4x³ + 2x²) + (x² + 1/2x) - (5/2x + 5/4) + 1/4 =
 - 2x²(2x+1) + 1/2x(2x + 1) - 5/4(2x + 1) + 1/4 =
 - (2x + 1)(2x² + 1/2x - 5/4) + 1/4
 
Quotient =  2x² + 1/2x - 5/4
Remainder = 1/4
<u>(b) 2x - 3</u>
- 4x³ + 3x² - 2x - 1 = 
 - (4x³ - 6x²) + (9x² - 13.5x) + (11.5x - 17.25) + 16.25 = 
 - (2x -3)(2x² + 4.5x + 5.75) + 16.25
 
Quotient = 2x² + 4.5x + 5.75
Remainder = 16.25
<u>(c) 4x - 1</u>
- 4x³ + 3x² - 2x - 1 = 
 - (4x³ - x²) + (4x² - x) - (2x - 1/2) - 3/2 =
 - (4x - 1)(x² + x - 1/2) - 3/2
 
Quotient = x² + x - 1/2
Remainder = - 3/2
<u>(d) x + 2</u>
- 4x³ + 3x² - 2x - 1 = 
 - (4x³ + 8x²) - (5x² + 10x) + (8x + 16) - 17 =
 - (x + 2)(4x² - 5x + 8) - 17
 
Quotient = 4x² - 5x + 8
Remainder = - 17
 
        
                    
             
        
        
        
Answer:
2 miles 
Step-by-step explanation:
10.2 (total amount of miles ran) - 2.2(fifth day) = 8m
8=miles ran in total for the first 4 days
8 miles / 4 days = 2 miles per day for the first 4 days
