Answer:
x = 1
Step-by-step explanation:
Sum the coefficients of the polynomial, that is
1 - 6 + 11 - 6 = 0
Hence x = 1 is a root and (x - 1) is a factor of the polynomial
Let's have a look:
2(4)= 8 (this would not work)
5(4)= 20 (this wouldn't work)
7(4)= 28 This does, let's check the others.
7(6)= 42 This does not work.
"D" would be the correct answer.
I hope this helps!
