Ugh I know the answer but like it wont let me take a pic of how to do it and the answer ugh sorry I will answer it as soon as I can
no real solutions
The conditions for the discriminant are
• If b² - 4ac > 0 then 2 real and distinct roots
• If b² - 4ac = 0 then 2 real and equal roots
• If b² - 4ac < 0 then no real solutions
30, ___, 19, 13.5
19 - 13.5 = 5.5
30 - 5.5 = 24.5
19 + 5.5 = 24.5
Thus, 30, 24.5, 19, 13.5.
