Solve quadratic equations by factoring
Questions at easy, medium and hard levels. Pick a level and get a fresh set every time, with instant feedback.
Learn it Move everything to one side so the equation equals 0, factor, and set each factor equal to 0 (the zero product property).
Example: Solve 2x² + 5x − 3 = 0.
- Factor: (2x − 1)(x + 3) = 0.
- 2x − 1 = 0 → x = 1/2, or x + 3 = 0 → x = −3.
- Roots: 1/2 and −3.
