What’s on the Factoring Out the GCF poster
The rule, 4 worked examples, and the mistake everyone makes.
- Find the largest factor common to every term and take it outside a bracket.
- 6x² + 9x = 3x(2x + 3)
- 4x³ − 8x² = 4x²(x − 2)
- 5x + 10 = 5(x + 2)
- x² + x = x(x + 1)
- Common mistake: x² + x = x(x) → x² + x = x(x + 1)
Always expand your answer to check. It takes three seconds and catches everything.
