Gave some feedback: Ready to use

#### Christopher Graham on Extract common factors of polynomials 5 months, 3 weeks ago

The pattern match on line 10 of the custom function no longer appears to handle the commutativity of the expression, despite using the doCommute option. E.g. $2*(17x+2)$ is not acccepted, however $(17x+2)*2$ is.

Saved a checkpoint:

Checkpointing before looking at the problem with the user defined function mark_factorised which no longer appears to be functioning correctly.

#### Christopher Graham on Complete the square and find solutions 6 months ago

Changed gaps to number entry, as they were not being marked correctly as mathematical expressions.

Gave some feedback: Ready to use

#### Christopher Graham on Find the equation of a line through two points - positive gradient 8 months ago

Fixed bug in correct line plot, caused by reading wrong student answer box (must have had a part added)

You're right! I've fixed it, and improved the TeX. Worried that I let that slip by!

In part b does not accept correct answer. Mistake also shown in the solutions.

I think there is a sign error in the second equation in part b.

#### Christian Lawson-Perfect on Substitute values into formulas 1 year, 4 months ago

Saved a checkpoint:

I've changed the definition of x2 to make sure the sales are always non-negative.
