Find the discriminant of the quadratic \(5x^2 - 2x + 8.\)
Here is the Quadratic Formula:
\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\) the b^2-4ac part is the discriminant 5x^2 -2x+8 a = 5 b = -2 c= 8
plug in those values and compute !
I got -164 which was incorrect. I did -2^2 - 4(5)(8) and got -164. Can you try again?
b^2 - 4ac would be (-2)^2 - 4 (5)(8) = 4 - 160 = - 156
Oh! Thank you thank you so much!
