What is the complete factorization of p(x)=32x5y−2xy5 over the integers?

egoroff_w [7]

Answer:

$p(x)=2xy(2x-y)(2x+y)(4x^2+y^2)$

Step-by-step explanation:

$p(x)=32x^5y-2xy^5=2xy(16x^4-y^4)=2xy(4x^2-y^2)(4x^2+y^2)\\\\\boxed{p(x)=2xy(2x-y)(2x+y)(4x^2+y^2)}$

The factoring of the difference of squares is applicable:

a^2 -b^2 = (a -b)(a +b)

Two trucks are traveling in the same direction, one going twice as fast as the other. At the end of 6 hours they are 204 miles a

TEA [102]

Answer:

34 mph and 68 mph respectively

Step-by-step explanation:

Step one:

given data

let the speed of the first truck be x mph

and the speed of the second truck be 2x mph

time taken = 6 hours

total distance = 204 miles

Step two:

from speed = distance/time

distance= speed*time

hence

2x*6-6x= 204

12x+6x= 204

6x= 204

divide both side by 6

x= 204/6

x=34 mph

The second truck was moving at

=2x

=2*34

=68 mph
