Saved a checkpoint:

Indeed it should! I've changed the pattern restriction to fix that.

#### Ben Brawn commented on Completing the square9 months, 3 weeks ago

I believe pattern should be (+-$n? *$v + +-$n)^2 + +-$n

Set accuracy to 0 so the exact value must be given, i.e. in terms of $\pi$ instead of a single decimal.

#### Christian Lawson-Perfect on Area of Triangle1 year, 4 months ago

Saved a checkpoint:

Fixed the measurements in drawingA

#### Christian Lawson-Perfect on Expanding Two Brackets1 year, 4 months ago

Saved a checkpoint:

Fixed the pattern restriction so a negative quadratic term with no coefficient is OK.

#### Christian Lawson-Perfect on Linear Equations1 year, 5 months ago

Saved a checkpoint:

Thanks! I've fixed both of those.

#### Tom Goodale commented on Linear Equations1 year, 5 months ago

There are a couple of typos in the pairs variable:

• In the first equation c should equal -5.5
• The third equation should have "-2" on the right hand side instead of "+2"
