Find and explain the error in the student's work/answers below

Question

Solve:
m²+m-6=0
m^2-2m +3m-6=0
m(m-2)+3(m-2)=0
(m-2)(m+3) =0
m-2=0orm+3=0
m =-2orm=3

Answer 1

The error in the student's work is the last step where they split the equation into two separate equations incorrectly. The correct step would be to split it as "m - 2 = 0 or m + 3 = 0", not "m = -2 or m = 3".
