Factor completely. Remember to look first for a GCF and to check by multiplying.
1. x2+4x+4
Both ends, the x^2 & the 4, are squares. Try that first.
2. x2-20x+100
Same comment
3. 64+16x+x2
Same comment
4. 9x2 - 42x + 49
Same comment
5. 36x2+96xy+64y2
Factor out 4 first, then same comment

1. x2+4x+4 = (x+2)^2
---------------------------
2. x2-20x+100 = (x-10)^2
---------------------------
3. 64+16x+x^2 = (8+x)^2
---------------------------
4. 9x2 - 42x + 49 = (3x-7)^2
---------------------------
5. 36x2+96xy+64y2 = (6+8y)^2
