Formula Response problems ask the student to type in a formula as an answer. If the answer is 2x²+4, the student is allowed to type "2*x*x+4", "x*x + x*x + 4", "2*x2 + 14 - 10", or any other equivalent expression. Formula Response problems have many of the same characteristics of Numerical Response problems, including the ability to run scripts, dynamically generate answers, etc.**** Unknown command \textasciicircum, (2 user-defined) Line 7
