Question 87069: Can you please help me with these 2 problems. Kidly show the solution and answer. Divide using synthetic division:
1. ( 2x5 – 4x – 18x3 – 28x2 – 25x -15 ) ÷ ( 2x + 3 )
2. ( 6x4 – 4x3 – 2x2 + 27x + 7 ) ÷ ( 3x – 4 )
***these are problems on polynomials, the number right after the x are its exponents...

Can you please help me with these 2 problems. Kidly show the solution and
answer. Divide using synthetic division: 
1. ( 2x5 – 4x4 – 18x3 – 28x2 – 25x -15 ) ÷ ( 2x + 3 )
2. ( 6x4 – 4x3 – 2x2 + 27x + 7 ) ÷ ( 3x – 4 )

Synthetic division only allows you to divide by binomials of the form
x ± b.  To divide by binomials of the form ax ± b you must factor out
a and get a(x ± b%2Fa). You then divide by (x ± b%2Fa) and then again by
a.


1. ( 2x5 – 4x4 – 18x3 – 28x2 – 25x -15 ) ÷ ( 2x + 3 )

So first factor 2 out of 2x + 3, getting 2(x + 3%2F2)

Now first, divide synthetically by the x + 3%2F2


-3%2F2|  2  -4 -18  -28  -25  -13    
    |    -3  21%2F2  45%2F4 201%2F8 -3%2F16
    ------------------------------------------------------------   
     2   -7-15%2F2 -67%2F4  1%2F8 -243%2F16

which gives you a quotient of 

     

Simplify the fraction on the right by multiplying top and bottom
by LCD = 48

     2x%5E4-7x%5E3-%2815%2F2%29x%5E2-%2867%2F4%29x%2B%281%2F8%29-729%2F%2848x-16%29


Now you have to divide everything by 2, which is to multiply
every term by 1%2F2

     
     
     

What a horrible problem your teacher gave you!  The other one looks just as
horrible.  Do it the same horrible way!

Divide using synthetic division:
1. ( 2x5 – 4x – 18x3 – 28x2 – 25x -15 ) ÷ ( 2x + 3 )
