So what is your question?
Are you finding the value of the discriminant, since that is your title?
the discriminant the the part under the square root sign of the quadratic formula, namely
b^2 - 4ac
in your equation,
a = 1
b = -7
c = 5
evaluate.
according to the choices given, you are probably supposed to state whether there are 2, 1 or no real solutions.
Do you not have any notes in your text or class-room notes that tell you about the nature of the roots vs the value of the discriminant??
v2 - 7v + 5 = 0
A. 2 B.1 C. 0
Ok, I am clueless on this one??
