Answer:

[tex] x = 6 , -2[/tex]

Step-by-step explanation:

Let the required number be x .

According to the Question ,

[tex]\implies x^2 - 12 = 4x \\\\\implies x^2 -4x -12 = 0 \\\\\implies x^2 -6x + 2x -12 = 0 \\\\\implies x(x-6)+2(x-6) = 0 \\\\\implies (x-6)(x+2)=0\\\\\implies \boxed{\boxed{ x = 6 , -2}}[/tex]

Hence the number can be 6 or -2.
