2. the number 1 is a zero of the polynomial p(x)=x^3−3x^2+7x−5.
a. write p(x) as a product of linear factors.
b. what are the solutions to the equation x^3−3x^2+7x−5=0?

(a) Factor will be (x-1)  x = 1 , -1+2i and -1-2i

(b) Solution of the equation will be                    

Step-by-step explanation:

We have given that 1 is the zero of the polynomial

(a) As x is zero of the polynomial so (x-1) will completely divide the polynomial

So

Now can be factorized as

So the linear factor of polynomial   will be

(x-1)

(b) Solution of the equation will be x = 1 , -1+2i and -1-2i

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
