The polynomial P(x) = x4 + 4x3 + 8x2 + 8x + 4 is the square of another polynomial Q(x) =
ax2 + bx + c with positive coecients a, b, and c. Compute 4a + 2b + c.	Choose the correct answer:
A) 2  B) 4  C) 6  D) 8  E) 10
Note that Q(2) = 4a+2b+c and P(2) = [Q(2)]2 = 24+4*23+8 * 22+8* 2+4 = 100.   Since a, b, and c are positive, we have Q(2) &gt; 0. Taking the positive square root, we get   Q(2) =√P(2) =√100 = 10 .   correct answer 10
