It is 14 because 8= 6to-2 and 3to-3is 6 so both together is 14

Answer:

Step-by-step explanation:
Given:
Center of circle is at (5, -4).
A point on the circle is 
Equation of a circle with center
and radius 'r' is given as:

Here, 
Radius of a circle is equal to the distance of point on the circle from the center of the circle and is given using the distance formula for square of the distance as:
Using distance formula for the points (5, -4) and (-3, 2), we get

Therefore, the equation of the circle is:

Now, rewriting it in the form asked in the question, we get

If it was typo and the original equation is 3x^2 - 10x - 8, then the answer would be (<span><span>3x+2)(x-4), but if not then IDK.
