Answer:

A. {x}^{3}  - x -  \frac{6}{2x + 3}

Step-by-step explanation:

\frac{2 {x}^{4}  + 3 {x}^{3}  - 2 {x}^{2}  - 3x - 6}{2x + 3}  \\  \\  = \frac{(2 {x}^{4}  + 3 {x}^{3} ) - (2 {x}^{2}   + 3x) - 6}{2x + 3}  \\  \\  = \frac{ {x}^{3} (2 {x}  + 3  ) - x(2 {x}  + 3) - 6}{2x + 3}  \\  \\  =  \frac{ {x}^{3} (2x + 3)}{2x + 3}  -  \frac{x(2x + 3)}{2x + 3}  -  \frac{6}{2x + 3}  \\  \\   \purple { \bold{=  {x}^{3}  - x -  \frac{6}{2x + 3}  }}

Complete the equation of the line through (3, -1) and (4, 7)​
nikitadnepr [17]

Answer:

  y = 8x -25

Step-by-step explanation:

The two-point form of the equation of a line can be used.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (7-(-1))/(4-3)(x -3) +(-1)

  y = 8(x -3) -1

  y = 8x -25 . . . . slope-intercept form of the equation

_____

We don't know what you're starting with, so we don't know how to "complete the equation." Perhaps the above equation is sufficient for the task.
