First question:

I urge you to perform the division using the synthetic division method:

      ________________
-4  /   1   3   -6   -6   8
             -4    4     8  -8
       -----------------------
         1   -1   -2    2    0

Note that there is no remainder.  When this is the case, the divisor (here, that's -4) is a root of the given polynomial, and the value of that polynomial, g(-4), is 0.

If the remainder were not 0, then the remainder represents the value of the polynomial for that particular divisor.  For example, if x = -3, the remainder is -28.  We'd write that as g(-3) = -28.

But here, g(-4) = 0.

What is the diameter of the circle whose center is at (6,0) and passes through the point (2,-3)
Aleksandr [31]

Answer: 10 units

Step-by-step explanation:

Use the distance formula(√(x1-x2)^2+(y2-y1)^2)

\sqrt{(6-2)^2+(0-(-3))^2} \\\\\sqrt{4^2+3^2}\\\\\sqrt{16+9}\\ \\\sqrt{25}\\ \\5

Thus, the radius of the circle is 5.  Because the diameter is 2r, the diameter = 2(5) = 10

Hope it helps <3
