Question

If `x/12 - 3/x` = 0, then the values of x are ______.

Options

• ± 6

• ± 4

• ± 12

• ± 13

Answer 1

If `x/12 - 3/x` = 0, then the values of x are ± 6.

Explanation:

`x/12 - 3/x` = 0

`(x xx x)/(12 xx x) - (3 xx 12)/(x xx 12) = 0`

`(x^2 - 36)/(12x) = 0`

x² − 36 = 0

x² = 36

x = ± 6
