Find the equation of the circle with center at (-1, 3) and radius of 4.

(x+1  )^2+(y−3)^2= 16

Step-by-step explanation:

We can write the equation of a circle as

(x−h)^2+(y−k)^2=r^2

Where (h,k) is the center and r is the radius

(x− -1  )^2+(y−3)^2= 4^2

(x+1  )^2+(y−3)^2= 4^2

(x+1  )^2+(y−3)^2= 16

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
