If (3x+1)2-14(3x+1)+49=0 then x= It'll always be 1 because of the "your original number" line that acts as a conversion factor.

Haven't done algebra for 5 years, but sure I'll give it a go. I think this is that perfect square stuff I did in highschool.

(3x+1)2-14(3x+1)+49=0 [(3x+1)-7] 2=0 (3x+1)-7=0 3x+1=7 3x=6 x=2
