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?

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.....cheeky
