How many roots does y=x5−4x2+3x have?

a
3

b
4

c
5

d
6

5 roots (answer C)

Step-by-step explanation:

Any polynomial should have in the Complex Number System, as many roots as the polynomial's degree.

In our case, since we are dealing with a polynomial of order 5 (degree 5), it should have 5 roots in the Complex Number System.

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
