I think it's 2 because the quadratic equation looks like this ax^2+bx+c=0 and option 2 looks like it.
Step-by-step explanation:
For option 1: x(x^2+1)=0
x^3+1=0 ( This also does not look like the quadratic function, so it couldn't be the answer)
For option 2: (x+3)(x+4)=5
x^2+3x+3x+12=5
x^2+6x+12=5 ( This does look like the quadratic function, so it could be the answer)

Answer:
it is 2
