Evidence Statement Text: 

Use the structure of a numerical expression or polynomial expression in one variable to rewrite it, in a case where two or more rewriting steps are required.
Clarifications, limits, emphases, and other information intended to ensure appropriate variety in tasks:

i) Example: Factor completely: x^2 - 1 + (x - 1)^2 . (A first iteration might give (x+1)(x-1) + (x-1)(x-1), which could be rewritten as (x-1)(x+1+x-1) 1) on the way to factorizing completely as 2x(x-1). Or the student might first expand, as x^2 – 1 + x^2 -2x+1, rewriting as 2x^2- 2x, then factorizing as 2x(x-1).) 
ii) Tasks do not have a real-world context.
