1. Question 13 marksGrade 7
   Solve $x^2 - 5x + 6 < 0$. [3]
   Show the worked solution

   Factorise: $x^2-5x+6 = (x-2)(x-3)$

What are the common mistakes in Quadratic inequalities?

When a pupil makes one of these on Revision Workshop, the marking engine names the mistake and explains it, instead of just marking the answer wrong.

• Shades or selects the wrong region for a quadratic inequality

  Chose the region OUTSIDE the roots instead of between them - for a "< 0" inequality with a positive $x^2$ coefficient, the solution is always between the roots

• Gives only the roots of a quadratic instead of the solution region for the inequality

  Found the correct critical values $x = 0$ and $x = 7$
