Contributor Illustrative Mathematics
This task has students combine polynomial arithmetic with pattern-matching. Students can expand powers of x+1 using either repeated multiplication (A-APR.1) or by the binomial theorem (A-APR.5), and then are asked to analyze the question of whether the similarity of coefficients with the digits of powers of 11 is a coincidence.
