4 0

Answer: (A) 2x² + 5x + 15 + \bold{\dfrac{48}{x-3}}

<u>Step-by-step explanation:</u>

x - 3 = 0   ⇒   x = 3

Using synthetic division:

3   |   2    -1     0    3

    <u>|   ↓     6    15   45 </u>        

        2     5    15   48 ← remainder

Factored polynomial is: 2x² + 5x + 15 + \dfrac{48}{x-3}

gulaghasi [49]
In a geometric progression:
a, b, c, d...

b/a = 112 / 64 = 1.75
c/b = 196 / 112 = 1.75
d/c = 343 / 196 = 1.75
The common ratio = 1.75
