Factoring special products
Printable practice with an answer key the engine computes, at three levels, in as many versions as you need.
Problem types
- x² − b², a difference of squares: x² − 49
- a perfect square, plus: x² + 6x + 9
- a perfect square, minus: x² − 10x + 25
- a²x² − b², a number on x²: 4x² − 9
- a GCF first: 2x² − 18
Sample Sheet · Level 1
