Answer:
9x^2
Step-by-step explanation:
Each of the coefficients can be divided by nine. You can factor each of them to show what the results would be.
The bolded part is what is common to each of them.
The highest common factor in all three that's a variable is x^2. You cannot take any more than that out of the three terms.
So the answer would be
9x^2
The HCF that can be taken out of the polynomial and the left over of the polynomial is
9x^2 ( 2x^2 - 3x - 4) This is not your answer but it helps you see what the answer means.
