  • Factorise a quadratic

    by Thomas Waters and 2 others

    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.
