I can't see how to apply inequalities to solve this equation unless we are looking for approximate values of the roots.

@@ViktorMath yes true.....I came up with approximate values too.....I thought you could help me out here to solve by using inequalities.....but anyways the solution you provided was excellent and it got my thinking right here as how to approach a problem....sometimes we get so critical that we forget that the problem may be simple one but we tend to think it otherwise...complexity at stupidity best😆😆😆 ...thanks anyways....hope to see more 😘😘😘
