Use the grouping method to factor the polynomial below

A

Step-by-step explanation:

Given

x³ - 5x² + 3x - 15 ( factor the first/second and third/fourth terms )

= x²(x - 5) + 3(x - 5) ← factor out (x - 5) from each term

= (x - 5)(x² + 3)

= (x² + 3)(x - 5) → A

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4

answer is  

c.
