The nature of roots of a quadratic equation can be determined from its discriminant.

Discriminant = b² - 4ac

b = coefficient of x term = 2
a = coefficient of squared term = 2
c = constant = 4

So,

Discriminant = 4 - 4(2)(4) = -28

Since the discriminant is negative, the two roots of the given equation will be complex .

Therefore, the answer to this question is option B

Ellie practices piano 2/3 h per day, several days each week. She practiced piano 32 2/3 hours during the summer. What equation c
SVEN [57.7K]

hello :)

so let me just give you the answer first:

2/3 * d = 32 2/3

here is why

so since the sentence said 2/3 PER day, then d (the number of days) multiplied by the time spent each day playing piano should give you how much time was spent in total over the certian number of days.

the 32 2/3 is just the amount of time ellie spent (as you have said)

so, this equation would be the correct one.

i hope this helped you out! please vote me for brainliest and have splendid day!
