The difference of the roots of the quadratic equation x^2 + bx + c = 0 is -2. Find the discriminant of the given equation.
What do I do here?
+36915 The quadratic formula for this quadratic will be -b +- sqrt(discrim) / 2 for the difference of the roots to be -2
+- 1 will need to be +- sqrt (discr)/2 the disc will need to be 4 then the sqrt of the discriminant will be 2 then divide by 2 and you will have the +- 1 for the roots to have a difference of 2 ... or -2
I don't think that is very clear.....
