Answer 1

HELLO DEAR,

${x}^{2} + { \frac{1}{ {x}^{2} } } - 4x + \frac{4}{x} + 6 \\ \\ = \frac{ {x}^{4} + 1 }{ {x}^{2} } - \frac{4 {x}^{2} + 4}{x} + 6 \\ \\ = \frac{ {x}^{4} + 1 - 4 {x}^{4} - 4 {x}^{2} }{ {x}^{2} } + 6 \\ \\ = \frac{ - 3 {x}^{4} + 14 {x}^{2} + 6 {x}^{2} }{ {x}^{2} } \\ \\ = \frac{ {x}^{2}( - 3 {x}^{2} + 20) }{ {x}^{2} } \\ \\ = - 3 {x}^{2} + 20$
I HOPE ITS HELP YOU DEAR,
THANKS
