Factoring the left and right parts separately gives:q3 - q2 + 2q - 2= q(q2 - 1) + 2(q - 1)= q(q + 1)(q - 1) + 2(q - 1)Now we have a common factor (q - 1) that we can take out. I'll combine the...
5x2 -605 is the same thing
First factor out the 5
5(x2 -121)
Now note this is the difference of squares
so we factor it as
5(x+11)(x-11)
and we are done!
