Answer:

(x+4)(x+2)

Step-by-step explanation:

Distributive property of 2 binomials:

First, outer, inner, last

(a+b)(c+d) = ac+ad+bc +bd

Factor x^2 into x*x

Factor 8 into 2*2*2

Find what two numbers add up to 6 and multiply to get 8

1 and 8 do not work because they add up to 9.  2 and 4 work because they add up to 6.  

Check: (x+4)(x+2)

First:  x*x = x^2

Outer: 2*x

Inner: 4*x

Last: 2*4 = 8

Add together: x^2+2x+4x+8 = x^2+6x+8

zepelin [54]

Answer:

(x -5)² + (y +4)² = 100 Should be the correct answer, hope this helps :)

Step-by-step explanation:

A circle centered at (h, k) with radius r will have equation ...

... (x -h)² + (y-k)² = r²

The point satisfies the equation for the circle. Filling in the given numbers, we have ...

... (x -5)² + (y+4)² = (-3-5)² + (2+4)² . . . . . . (h, k) = (5, -4), (x, y) = (-3, 2)

... (x -5)² + (y +4)² = 64 +36
