Step-by-step explanation:
We have,
If a quadratic equation with real coefficients has a discriminant of -36.
The general form of quadratic equation is :
The discriminant of this equation is :
If D=0, it will have 1 real roots
If D>0, it will have 2 real roots
If D<0, it will have no real roots
We have,
D = -36 < 0, so, the quadratic equation will have no real roots.
We can't find explicit values for and
, since there is only one equation, but two variables.
The best we can do is solve for one variable with respect to the other:
Solve for :
subtract from both sides:
divide both sides by :
Solve for :
subtract from both sides:
divide both sides by :
