Question

Two students, Jennifer and Jamal, factored the trinomial 6x^2 − 3x − 9. Jamal factored it as 3(2x − 3)(x + 1) and Jennifer factored it as (2x − 3)(3x + 3). Indicate which student factored the trinomial completely and which student did not, and explain why.

Answer 1

$6x^2-3x-9=(3x+3)(2x-3)=3(x+1)(2x-3)$ so Jamal factored completely.
