yea its part of the quadratic formula

note that your quadratic equation is given to you : \[-x^2 -12x + 4 = 0 \] and it's written in the form: \[ax^2 + bx + c = 0 \] So identify your "a" , "b" and "c" values and then plug it into the discriminant formula: \[\Delta = b^2 - 4ac\]

So the rules of the discriminant, \(\Delta\) : \(\Delta \gt 0\) , 2 real roots \(\Delta =0\) , 1 real root \(\Delta \lt 0\) , 2 complex roots (with i)
