Answer 2

Answer:

(C) 4

Step-by-step explanation:

Let the number be x

then according to the question :

$x {}^{2} - x \: = 12$

$x {}^{2} - x \: - 12 \: = 0$

$x {}^{2} - 4x \: + 3x - 12 = 0$

$x(x - 4) \: \: \: \: 3(x - 4) = 0$

$(x + 3) \: \: \: (x - 4) = 0$

$x = - 3 \: \: \: or \: x = 4$

Now ,

we know that a number cannot be negative so the value of x is 4.

The number is 4
