Absolute value is a by definition, the consideration of the negative and the positive regions of any given function, variable or expression. Therefore, in order to take that away, you have to split the original equation, to the two following equations, and solve them independantly: \[1) 4x^3-5x=(4x)\] \[2)4x^3-5x=-(4x)\]

watch out for the domain true. 4x^3 - 5x = 4x if x > 0 and 4x^3 - 5x = -4x if x < 0 and if x = 0, then 0 = 0 (true), hence 0 is also one of the solutions

watch out for the domain *too*
