Quadratic Equation Knowledge (QEK)

Measures how well you understand and can apply core concepts and methods for solving and interpreting quadratic equations.

Foundations to revisit

Developing knowledge

Strong knowledge

0 – 6: Foundations to revisit | 7 – 12: Developing knowledge | 13 – 16: Strong knowledge

A score of 2 falls in the Foundations to revisit range, suggesting you may benefit from reviewing standard form, roots, signs, and the main solving methods before tackling more mixed problems.

SAMPLE QUESTIONS

Example Questions From the Test

- 3x^2 - 2x + 7 = 0, with the constant sign changed
- 3x^2 + 2x - 7 = 0, with 2x moved using the wrong sign
- 3x^2 - 2x - 7 = 0, after subtracting 2x from both sides
- 3x^2 - 9x = 0, after incorrectly combining unlike terms
- 10 metres, found by treating the area as a perimeter
- 8 metres, which would make the area 88 square metres
- 4 metres, which would make the area 28 square metres
- 5 metres, since 5(5 + 3) = 40
- x^2 + 3x - 10 = 0, which has the wrong sum of roots
- x^2 - 3x - 10 = 0, obtained from (x + 2)(x - 5) = 0
- x^2 - 7x + 10 = 0, which represents roots 2 and 5
- x^2 + 3x + 10 = 0, which uses the wrong constant sign

These are 3 of the 16 real questions — the rest appear in the test. No sign-up needed to start.
