What are the excluded values for x for x+4/-3x^2+12x+36

C) -2, x=6

Step-by-step explanation:

we are given

we know that

values of x excluded when that value of x makes f(x) undefined

and any function is undefined when it's denominator becomes 0

so, we set denominator =0

and then we solve for x

we can factor out

we get

so, excluded values are

..............Answer

the answer will be the last one

(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
