Question

Determine # of solutions: 1/3x2- 5x +25

Answer 1

Sorry =0*

Answer 2

From (1/3)x^2-5x+25, we see that a = 1/3, b = -5 and c = 25



D=b^2-4ac



D=(-5)^2-4(1/3)(25)



D=25-4(1/3)(25)



D=25-100/3



D=-25/3



So the discriminant is D=-25/3



Since the discriminant is less than zero, this means that there are two complex solutions.



In other words, there are no real solutions.

Answer 3

So the formula to find a discriminant is b^2-4ac?

Answer 4

yep, that's it

Answer 5

Thanks so much!
