Answer:
The required equation in standard form is 
Step-by-step explanation:
The equation of a circle with center (h,k) an radius, r units is given by the formula;

The given circle has center (-2,0) and radius squared can be calculated from the given area, which is 


We substitute these values into the formula to obtain;

We simplify to get;

Step-by-step explanation:
f(x)=(2×2)-3x+20
0=4-3x+20
0=-3x+24
3x=24
×=24÷3
x=8
