Each term in the second factor is multiplied by each term in the first factor, that is

x(x - 2) + 6(x - 2) ← distribute parenthesis

Write an equation of the circle with center (-2,5) radius 9

Answers

Answer:

(x+2)²+(y-5)² = 81

Step-by-step explanation:

The formula for calculating equation of a line is expressed as

(x-a)²+(y-b)² = r²

(a,b) are the points

r is the radius

Given

Point = (-2,5)

Radius = 9

Substitute

(x-(-2)²+(y-5)² = 9²

(x+2)²+(y-5)² = 81

Hence the required equation is (x+2)²+(y-5)² = 81
