Possible name change: Factor Theorem on a polynomial MCQ 

If you would like it written in a simpler way.

Question:

Typo, 'Factor of f(x)' rather than Factors. 

Advice:

Nothing to change here. Personally I would remove the commas after each line of the equation but they do not need to be omitted.

Before I even look at this question: never say "basic"!!!

I've fixed a couple of typos, but otherwise this is OK!

I have deleted the part d) from this question and added in a much simpler question on squaring fractions.

I've added a script to make sure the answer is fully factorised.

Will try to add an image from inkscape to this as well, but just thought i'd set its status to "Needs to be tested" in the meantime.

This looks good! I changed a few words to sound more natural in English.

Do each of the subparts assess different things? If not, you might as well just have one of each - the student can click "try another question" if they want more.

The advice for part c doesn't show how to enter the answer. Students can't type $\sqrt[4]{x}$, so you need to say something like, "enter this as x^(1/4)", or add a line "$ = x^{1/4}$" to the end of the working-out.

I'm not keen on the sudden appearance of $n$ in the advice for part d! I think you're just shuffling things around to show what you've already been given. The expressions you have to resolve are all just stock identities, so I don't think there's anything to explain.

Christian Lawson-Perfect on Quadrant coordinates MCQ 8 years, 6 months ago

Gave some feedback: Has some problems

Christian Lawson-Perfect commented on Quadrant coordinates MCQ 8 years, 6 months ago

Name the quadrants A,B,C,D instead of 1,2,3,4. Or could you give them compass coordinate NW,NE,SW,SE? Trying to keep two coordinate numbers in your head and then remember a number for the corresponding quadrant will tax some minds! It sounds silly but difficulty with holding numbers in your head is much more common than you'd think.

It looks like part a is always in the top-right quadrant, and similar for the next three parts. If you replace parts a to d with a "match choices with answers" part, you can shuffle the order of the choices, so that the answer isn't the same every time.

You could do the same with parts e to g.

The explanation at the top of the advice is very wordy and hard to follow. Here's my version:

You can think of a pair of coordinates as a directions to the desired point, starting from the origin.

The first part of the coordinates tells you how far to move along the horizontal $x$-axis. Positive numbers are on the right and negative numbers are on the left.

The second part of the coordinates tells you how far to move along the vertical $y$-axis. Positive numbers are above the origin and negative numbers are below.

For each part, something like "the first part is positive and the second part is negative, so the point lies in quadrant 3".

Lots of spelling mistakes - "coordiante", "axsis".

"All points on the x-axis correspond to a y value of 0, so we can assume that anything on the line y=0 is on the x-axis." is a little bit wrong. We don't assume anything. By definition, points with zero $y$ coordinate are on the $y$ axis.

For $(0,0)$ - your explanation is very long-winded. You can just say "the $x$ coordinate is 0 so it's on the $x$-axis, and the $y$ coordinate is zero so it's also on the $y$ axis."

Check the order of the parts in the advice.
