Question

plz help me as fast as you can....​

Answer 1

Step-by-step explanation:

GIVEN

$3x + \frac{1}{x} = 6$

squaring on both sides,

${(3x + \frac{1}{x} }^{2} ) = {6}^{2}$

${9x}^{2} + \frac{1}{ {x}^{2} } + 2(3x)( \frac{1}{x} ) = 36$

${9x}^{2} + \frac{1}{ {x}^{2} } + 6 = 36$

${9x}^{2} + \frac{1}{ {x}^{2} } = 36 - 6$

${9x}^{2} + \frac{1}{ {x}^{2} } = 30$
