Answer:

(x + 3)(x - 7)

(x + 1)(x - 2)

Step-by-step explanation:

The general form of factored equations :

y = (x + a)(x + b) [it can be ±, so don't worry about that part]

===============================================================

Hence, the expressions which are in factored form :

⇒ (x + 3)(x - 7)

⇒ (x + 1)(x - 2)

What is 3x^2-2n-5=0 please help me!!!

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
