Question

(6+5/x)²
pls help me​

Answer 1

36 +
`(60)/(x)` +
`(25)/(x^2)`

Explanation:

(6 +
`(5)/(x)` )²

= (6 +
`(5)/(x)` )(6 +
`(5)/(x)` )

Each term in the second factor is multiplied by each term in the first factor, that is

6(6 +
`(5)/(x)` ) +
`(5)/(x)` (6 +
`(5)/(x)` ) ← distribute parenthesis

= 36 +
`(30)/(x)` +
`(30)/(x)` +
`(25)/(x^2)` ← collect like terms

= 36 +
`(60)/(x)` +
`(25)/(x^2)`
