Find an equation of the circle whose diameter has endpoints (1,-4) and (-3,6).

Step-by-step explanation:

To find the equation of this circle, we must know the center and the radius.

We can find the radius by dividing the value of the distance formula by 2 (since ):

We can then find the center of the circle by averaging the coordinates:

Then, we substitute these values into the equation of a circle:

answer: 45

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p
