Saved a checkpoint:

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

#### Ben Brawn commented on Completing the square 9 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.

Saved a checkpoint:

Fixed the measurements in drawingA

#### Christian Lawson-Perfect on Expanding Two Brackets 1 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 Equations 1 year, 5 months ago

Saved a checkpoint:

Thanks! I've fixed both of those.

#### Tom Goodale commented on Linear Equations 1 year, 5 months ago

There are a couple of typos in the

pairsvariable:

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