@TysonA7med
Divide everything by three. x^2+kx/3+4=0
Now: (a+b)^2=a^2+2ab+b^2.
b may be either +2 or - 2
Therefore kx/3=2x*2 or kx/3=2x*(-2)
Solve for k and you get k=12 or k=-12
It is impossible for k to be +12 therefore it must be -12.
PS:
I dunno if it's common knowledge or not so: 3^2 means three squared and 4*5 means 4 times 5. I'm just not sure cuz it's used mostly in the programming and stuff.

@TysonA7med do they tell you how many solutions there are?

didn't help me, factoring the same number out of each term was not the answer. Next time do more than one type of problem please.
