If m is a real number and 2x^2+mx+18 has two distinct real roots, then what are the possible values of m? Express your answer in interval notation.
+36916 discriminant will have to be POSITIVE to have 2 real roots
b^2 - 4ac > 0
m^2 - 4(2)(18) >0
m^2 > 144
m > 12
m < -12 you can write it in interval notation......right?
