Question in AJAY's workspaceThis is a new and easy way for solving quadratic equation. It is based on the property that the roots are equidistant from the average.

Question in All questions
Two quadratic graphs are sketched with some area beneath them shaded. Question is to determine the area of shaded regions using integration. The first graph's area is all above the $x$axis. The second graph has some area above and some below the $x$axis.

Question in All questions
A quadratic equation (equivalent to $(x+a)^2b$) is given and sketched. Three equations are given that can be solved using the graph. There is a chance there will only be one solution.

Question in All questions
A few quadratic equations are given, to be solved by completing the square. The number of solutions is randomised.

Question in All questions
A quadratic function is given. The graph of the function is drawn with three coordinates on the graph, without any x or y ticks. The $x$ coordinate is given for a couple and $y$ coordinate given for the third, and coordinates are asked for.

Question in MATH6058 Engineering Maths 1
Factorise three quadratic equations of the form $x^2+bx+c$.
The first has two negative roots, the second has one negative and one positive, and the third is the difference of two squares.

Question in Demos
Give the student three points lying on a quadratic, and ask them to find the roots.
Then ask them to find the equation of the quadratic, using their roots. Error in calculating the roots is carried forward.
Finally, ask them to find the midpoint of the roots (just for fun). Error is carried forward again.

Question in Shivendra's workspace
A graph is drawn. A student is to identify the derivative of this graph from four other graphs.
Version I. Graph is quadratic
Version II. Graph is horizontal
Version III. Graph is cubic
Version IV. Graph is sinusoidal

Question in Fundamentals of Mathematics
Quadratic factorisation that does not rely upon pattern matching.

Question in Howtos
Show one of several blocks of text depending on the value of a question variable.
As well as a simple check for the value of a variable, the condition to display a block of text can be a complex expression in any of the question variables  in this example, depending on the discriminant of the generated quadratic.

Question in Howtos
The student is asked to factorise a quadratic $x^2 + ax + b$. A custom marking script uses pattern matching to ensure that the student's answer is of the form $(x+a)(x+b)$, $(x+a)^2$, or $x(x+a)$.
To find the script, look in the Scripts tab of part a.

Question in Howtos
Student is asked whether a quadratic equation can be factorised. If they say "yes", they're asked to give the factorisation.
