36 \int\limits^1_0 { \frac{1}{(2 x + 1) ^{3} } } \, dx =
u = 2 x + 1,  d u = 2 d x,  d x = d u / 2
36*1/2 \int\limits^1_0 {u ^{-3} } \, du = 18 * t ^{-2}/(-2) = \\ - 9 * t^{-2}= \\ -9 * ( 2 x + 1 ) ^{-2}
- 9 / ( 2 + 1 )² - ( - 9 / ( 0 + 1 )² = 
- 9 / 9 + 9 = - 1 + 9 = 8

Which of the following shows the division problem below in synthetic division form? 4x^2-13x+8 / x+5
Tju [1.3M]

Answer:

Dividing 4x^2 - 13x + 8  by x + 5 or x - (-5), in synthetic division form:

-5)        4          |       -13      |          8

           ↓               4 x (-5)     (-5) x (-33)  

           4                 -33               173

=> Quotient is 4x - 33 and remainder is 173

=> (4x^2  - 13x + 8)/(x + 5) = (4x - 33) + 173/(x + 5)

Hope this helps!
