SOLUTION: Here is a sample problem similar to the one I am having trouble with: (6+4{{{sqrt(7)}}})(6-4{{{sqrt(7)) and this was my attempt: (6+4{{{sqrt(7)}}})(6-4{{{sqrt(7)}}})=6^(2)

Question 260213: Here is a sample problem similar to the one I am having trouble with:
(6+4)(6-4)(6-4)=6^(2)-^(2)=36-7=29
(Correct answer is -76) But I am not sure how to get there.
Answer by Alan3354(69443) (Show Source): You can put this solution on YOUR website!
(6+4)(6-4)(6-4)=6^(2)-^(2)=36-7=29
(Correct answer is -76)
-------------------------------
You show 3 binomials, I think there should be 2, and you left out the 4.

=
= 36 - 16*7 = 36 - 112
= -76
