In case you’re having trouble reading the kid’s work, and because the top of the question is cut off, I’m going to reproduce the problem in text below the image:

Question: What is the product of \frac{x^2-1}{x+1} and \frac{x+3}{3x+3} ?

Answer: \frac{3x^2-3}{3x+3}*\frac{x+3}{3x-3}

\frac{3x^2+9}{9x+9} \rightarrow \frac{1x^2+3}{3x+3}


The usual: What does he know, what doesn’t he know, and what would you do next?
