4x2 + 8x + 4 = 4 (x2 + 2x + 1) = 4 (x + 1)2
3 x 1/2 = 3/2 or 6/4. If you're adding 7/4 and 3/4 to that, the answer is 16/4, which equals 4.
If that's 4 and 6/12 - 2 and 1/12, the answer is 2 and 5/12
x - 4x + 4 = -3x + 4 which cannot be factorised.

1/8 plus 1/4 plus 1/2 = 7/8 or 0.875
((2 plus (1 over 4)) plus 3) plus (7 over 8) = 6.12500
4 over 8 is the same as 1 over 2, so 1 over 2 plus 1 over 2 (.5+.5 OR 1/2 +1/2) is 1. The answer is 1.
2 over 3 plus 4 1 over 4 = 59/12 or 411/12

4 over 1 is 4. 2 + 4 is 6.
1/4 + 1/4 = 2/42/4 + 2/8 = 3/4
