Question

Calculate the discriminant and use it to determine how many real-number roots the equation has.

3x^2 – 6x + 3 = 0

A. three real-number roots

B. two real-number roots

C. one real-number root

D. no real-number roots

Answer 1

\[\Delta=b^2-4ac\]
\[a=3\] \[b=-6\] \[c=3\]

Answer 2

if the discriminant is less than 0, there are no real solutions
if the discriminant is equal to 0, there is one real solution
if the discriminant is larger than 0, there are 2 real solutions

Answer 3

wich one is it

Answer 4

try working it out for yourself
