Given: x2 - 8x + 5 = 0

A) Find the value of the discriminant.

B) State the number and type of roots/solution/zeros.  {2 real, 2 imaginary, or 1 real}

Answer 1

x² - 8x + 5 = 0

 

a = 1

b = -8

c = 5

 

(A)

 

D = √(b² - 4ac)

 

Just plug in the values of a, b, and c, and evaluate the discriminant.

 

(B)

 

If D = 0, then there is 1 real root of multiplicity 2

If D > 0, there are 2 different real roots

If D < 0, there are 2 different COMPLEX roots

 

You have everything you need to answer the question.
