Question

can someone help me understand this one?

Square the binomial

(6x-5)^2

Answer 1

start with
\[(6x-5)(6x-5)\]and then do the four multiplications

Answer 2

either that, or memorize that
\[(a-b)^2=a^2-2ab+b^2\] and replace \(a\) by \(6x\) and \(b\) by 5

Answer 3

6 by 5 is 30 right

Answer 4

By\[(a-b)^2 = a^2 -2ab+b^2\]
..satellite beats me to it >.>

Answer 5

if you'd like to learn a method in these things you can check this out http://openstudy.com/users/lgbasallote#/updates/4f9dda4ae4b000ae9ed25338

but what satellite said about expanding and multiplying is a suggested method because it is precise and you cannot go wrong with it rather than memorizing a formula :D

Answer 6

how can you not know what 5 times 6 is ? o.o
