What is 3x^2-2n-5=0

The answer to your question is: 
It is a quadratic equation in ’x’, with ’n’ mistakenly typed in the second term.

Although you didn’t ask for the solutions to the equation, I’m already here
so I might as well go through it and find them:

3x² - 2x - 5 = 0

In terms of the generic quadratic formula:
A = 3
B = -2
C = -5

Plug those into the quadratic formula, and you discover that

x = -1
and
x = ⁵/₃

\( 3x^2-2x-5=0 \)

\( (3x-5)(x+1) = 0 \)

\( 3x-5=0 \)

\( 3x=5 \)

\( x= \frac{5}{3} \)

\( x+1 =0 \)

\( x=-1 \)

\( x=-1, \frac{5}{3} \)
