A diameter of a circle has endpoints P(-10, -2) and Q(4, 6) A: Find the center of the circle.
B: Find the radius. If your answer is not an integer, express it in radical form.
C: Write an equation for the circle.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

b. f(x) = –√x + 3this is the correct answer
