Question

find the value of n from given equation

Answer 1

$\frac{57n}{2} - \frac{ {3n}^{2} }{2} = 0$
$\frac{57n - 3 {n}^{2} }{2} = 0$
$57n - 3 {n}^{2} = 0$
$3n(19 - n) = 0 \\ divide \: both \: sides \: by \: 3$
$n(19 - n) = 0$



Here, we can apply this property,

If '
$a \times b = 0$
then
$a = 0 \\ \\ or \\ \\ b = 0$
therefore

Here,
$n(19 - n) = 0 \\ \\ n = 0 \\ \\ or \\ \\ (19 - n) = 0 \\ \\ n = 19$
$hence \\ \\ n = 0 \\ \\ or \\ \\ n = 19$
