Answer 2

factor out the top equation.

Answer 3

thats your first one, good luck on the second :D

Answer 4

both of them can be factored
the one on the bottom
has the form

difference of squares
a^2 - b^2 = (a+b )(a-b)

Answer 5

well you have to know this

difference of squares

and

sum of squares

Answer 6

these are very impotant

difference of squares
( a - b )^2 = a^2 - b^2 = (a+b )(a-b)

sum of squares
a^3 + b^2 = (a+b)^2 -2ab
