Bart uses the factor theorem to determine whether x−4 is a factor of 3x^4−10x^3+11x−172 .

Bart uses the factor theorem to determine whether  x−4 is a factor of 3x^4−10x^3+11x−172 .

How does he proceed to the correct answer?

Bart evaluates  3x^4−10x^3+11x−172 when x = 4. He determines that the value of the expression is 1192, and concludes that  x−4 is a factor.

Bart evaluates  3x^4−10x^3+11x−172 when x=−4 . He determines that the value of the expression is 1192, and concludes that  x−4 is not a factor.

Bart evaluates  3x^4−10x^3+11x−172 when x=−4 . He determines that the value of the expression is 0, and concludes that  x−4 is a factor.

Bart evaluates  3x^4−10x^3+11x−172 when x = 4. He determines that the value of the expression is 0, and concludes that  x−4 is a factor.

 

i think it is C?
