Question 4 of 10 According to the synthetic division below, which of the following statements
are true?
Check all that apply.
2)3 -11 10
6 - 10
3 -5 0
A. (3x2.11x + 10) - (x + 2) = (3x-5)
I B. (x + 2) is a factor of 3x2 - 11x + 10.
I C. (x-2) is a factor of 3x2 - 11x + 10.
D. The number 2 is a root of F(x) = 3x2 - 11x + 10.
D E. The number -2 is a root of Fx) = 3x2 - 11x + 10.
F. (3x2 - 11x + 10) - (x - 2) = (3x - 5)

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

sorry, i don't know i just need points, i'm new here. chao
