Step-by-step explanation:
I posted my answer here: https://brainly.com/question/13060235
Considering that the lowest value for [tex]x[/tex] being 0 is not the correct approach and is not correct.
I will not type it again, but for [tex]x = \dfrac{1}{5}[/tex] I have got [tex]|5x^2 - 16| + |10x - 2| = 15.8[/tex], which is, at least, lower than 18.
Check my answer in the OP questions and any doubts just ask me.
