Question

find the general term (X2 minus 2byx)9
$( {x2} - \frac{2}{x} )9$


​

Answer 1

steps of solution

• (2x - 2/x) 9
• 18x - 18/x
• $(18 {x}^{2} - 18) \div x$
• let above equation be equal to 0
• $18 {x}^{2} - 18 = x$
• $18 {x}^{2} - x - 18 = 0$

This is required general term and

Here

$a = 18 \\ b = - 1 \\ c = - 18$
