To add the given expressions, we need to expand them first:
x(x+1)₂ = x² + x
x(x+1)₂ = x² + xx(x+2) = x² + 2x
x(x+1)₂ = x² + xx(x+2) = x² + 2xx(x+3) = x² + 3x
Now we can write the sum as follows:
x(x+1)₂ + x(x+2) + x(x+3) = x² + x + x² + 2x + x² + 3x
= 3x² + 6x
To evaluate the sum for x=1/2, we substitute x=1/2:
3x² + 6x = 3(1/2)² + 6(1/2) = 3/4 + 3 = 15/4
Therefore, the sum is 15/4 when x=1/2.
To evaluate the sum for x=0.2, we substitute x=0.2:
3x² + 6x = 3(0.2)² + 6(0.2) = 0.12
Therefore, the sum is 0.12 when x=0.2.
