THREE QUESTIONS CONCERNING QUADRATIC EQUATIONS: (a) State the four methods used to solve quadratic equations (b) Name the four types of solution types used to classify quadratic equations particularly when the discriminant is used. (c) The discriminant of a quadratic equation is -25. What type of solution(s) does the equation have?

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)

hm let me think hm think think hm think yes

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"
