Question

Can anyone walk me through the steps for this quadratic formula including what the discriminant is step by step?

-x^2 - 3 +5 = 0

anonymous · Answer

i assume your equation is $$-x^2 - 3x + 5 = 0$$
yes?

radar · Answer

-11 is not a perfect square, the coefficients are integers, so the solutions will be two nonreal complex values.

radar · Answer

Use the quadratic formula to solve.

radar · Answer

$$-(-3)\pm \sqrt{-3^{2}-4(-1)(5)} \over 2(-1)$$$$3\pm \sqrt{9+20}\over -2$$ please note the error I made in the solution of the discriminate which should be 29 rather than -11.  Thus since it is positive there will be two irrational solutions.  $$3\pm \sqrt{29}\over -2$$

*Correction to the earlier offending post:
a= -1
b= -3
c= 5 
discriminant = b^2 - 4ac that would be (-3)^2 - 4(-1)(5)= 9+20= +29 or it is positive.
What does that tell you about the zeroes or solutions?
