This is a poor definition because it is not descriptive. If you would have said, "Elephants are an animal that have gigantic feet and gigantic bodies. Elephants also have a trunk that they use to drink water. Along with the trunk elephants also have a mouth." Yes elephant are a gigantic animal, but you have to have reasoning something to back it up or just make it more unique.
You can use the discriminant rule, which is :
b^2 -4ac
“exactly one solution” means that it is equal to zero
so:
b^2 -4(4)(9)=0
b^2 -4(36)=0
b^2 -144=0
b^2=144
square root both sides
b=12 or -12
hope this helps !
