|4b - 4| + |3 - b³| + 2b³
subtitute b = 2 to the expression
|4·2 - 4| + |3 - 2³| + 2·2³ = |8 - 4| + |3 - 8| + 2·8 = |4| + |-5| + 16 = 4 + 5 + 16 = 25
---------------------------------------------
|4b - 4| + |3 - b²| + 2b³
|4·2 - 4| + |3 - 2²| + 2·2³ = |8 - 4| + |3 - 4| + 2·8 = |4| + |-1| + 16 = 4 + 1 + 16 = 21
