Factoring out the GCF
Printable practice with an answer key the engine computes, at three levels, in as many versions as you need.
Problem types
- a number out front: 6x + 9
- a number and x out front: 6x² + 9x
- three terms: 4x³ − 8x² + 12x
- a negative lead: −4x² − 8x
- two letters: 6x²y + 9xy²
Sample Sheet · Level 1
- 10x + 18 =
- 20x + 16 =
- 6x + 12 =
- 8x + 40 =
- 5x² + 45x =
- 30x² + 50x =
- 9x² + 72x =
- 24x² + 40x =
