find the discriminant of the quadratic equation x2 + 14x + 8 = 0 and use it to determine the number and types of solutions.

b2 − 4ac

228; two real solutions
228; one real solution
164; two nonreal solutions
164; two real solutions

D

Step-by-step explanation:

discriminant=b^2-4ac=14²-4×1×8=196-32=164>0

two real solutions.

I believe the answer is 164; Two real solutions

Explanation: I did the work and plugged in the numbers into b^2 - 4ac and got 164.

207/8 is the right

0.02

step-by-step explanation:

time of 9 192 631 770 periods of the radiation corresponding to the transition between the 2 hyperfine levels of the ground state of the caesium 133 atom at 0 k (but other seconds are sometimes used in astronomy)
