Triangle DEF is rotated 180 degrees about the origin to form triangle D'E'F'.What are the coordinates of the vertices of triangle D'E'F'? D' (–1, –4); E'(–2, –1); F'(–1, –5)

D' (4, 1); E'(1, 2); F'(5, 1)

D' (1, –4); E'(2, –1); F'(5, –1)

D' (4, –1); E'(1, –2); F'(1, –5)

(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
