- How many real roots does the equation have? x²+3x+4=0
Question 1:
How many real roots does the equation have? x²+3x+4=0 A. 0
Feedback Formula: Discreminent (D) = -b²-4ac => a=1, b=3, c=4
D = 32 - 4 * 4 = -7 < 0
So the equation has 0 real roots.
D = 32 - 4 * 4 = -7 < 0
So the equation has 0 real roots.
B. 1
C. 2
D. 3
