Question

Use the discriminant to determine the number and type of solutions the equation has.

x2 + 6x + 12 = 0

A.
two rational solutions

B.
no real solution

C.
one real solution

D.
two irrational solutions

Answer 1

discriminant is: \[b ^{2}-4ac\] this is from the quadratic formula..
if \[b ^{2}-4ac >0\] it will have two rational solutions
if \[b ^{2}-4ac <0\] it will not have any solutions
if \[b ^{2}-4ac =0\] it will only have one root
