Question

10n^{2} - 12 = -8 Please help

Answer 1

The value for n is $\frac{\sqrt{10} }{5}$

solving for n

given data

10n^{2} - 12 = -8

making n the subject of the formula

10n^{2}  = -8 + 12

10n^{2}  = 4

divide through by 10

n^{2}  = 4 / 10

finding the square root of both sides

n = square root ( 4 / 10 )

$n = \sqrt{\frac{4}{10}$

n = 0.632 or $\frac{\sqrt{10} }{5}$
