Question

`2nx^(2) +15n+7\\`

Answer 1

x = ± √(-15n-7) / √2n (± (-15n-7)^(1/2) / (2n)^(1/2))

Explanation:

Factoring?

2nx² + 15n+7 = 0

2nx² + 0*x + (15n+7) = 0 ... ax²+bx+c=0

Roots: x = (-2b ± √b²-4ac)) / 2a = (0 ± √0-4*2n*(15n+7)) / 4n

x = ± (√8n (-15n-7)) / 4n = ± (2√2n(-15n-7)) / 4n = ± (√2n(-15n-7)) / 2n

or x = ± √(-15n-7) / √2n
