chaise · Answer

(a+b)^2=a^2+2ab+b^2   <--- this is a perfect square if (ab/2)^2=b
(a-b)^2=a^2-2ab+b^2
(a-b)(a+b)=A^2+B^2

Does this help at all?

what are the factors of +9 that add up to-6
-3, -3 
(x-3)(x-3)  which is (x-3)^2

triciaal · Answer

for 2) refer to the response by @chaise

triciaal · Answer

m2 + 16m + 64 
what are the 2 factors of 64 that add up to 16 the signs are important
8
(m +8)(m + 8) = (m +8)^2
