Part of the graph representing an electrical signal is shown. the voltage rises steadily from an initial value (a) to a maximum value (b). it then drops instantly to the initial value (c) and repeats such that ab || cd and bc and de are vertical. if a = (1, 1) and b = (4, 3), what is the equation of cd ?
-3y − 2x = 5
3y − 2x = 5
3y − 2x = -5
3y + 2x = 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
