Correct answer would be b. x-10. You can check this by writing out (x-10) and writing the other factor out. Then simplify (factor) out everything and you will get x^2 - 21x + 110.
Answer:
3x(x-1)
Step-by-step explanation:
y = 
Factors are:
3x, (x-1)
Intercepts are:
3x = 0 , x = 0
x - 1 = 0, x = 1
To get X and Y by itself, move everything else to the other side of the equal sign. Do this by doing the opposite operation.
Example: x-2y=11
add 2y to both sides to get x by itself
x=2y+11
6x^2 / 45x = 6x / 45
6x / 45 = 2x / 15
