Ninth graders learn to factor polynomials — the reverse of multiplying — breaking expressions like x² + 5x + 6 back into their factors (x + 2)(x + 3), a key skill for solving quadratic equations.
Students will be able to…
Multiplying (x + 2)(x + 3) gives x² + 5x + 6. But can you run it in REVERSE — start with the polynomial and find the factors? That’s factoring.
Project this and match each polynomial to its factored form — tap a polynomial, then tap its factors.
Tap any phase to open the teacher moves and student actions.
(x+2)(x+3) = x²+5x+6 — can you go backward?
