Answer:
in the 1st row, one x^2 is positive while the other is negitive, making the total zero. also in the top row 8x+(-6x) = 2x, but in the 2nd row is says -2x, showing they are not the same. Also there is no -1/2 in the 2nd row like there is in the 1st row
Step-by-step explanation:
Recognize the differnce of 2 perfect squares
a²-b²=(a-b)(a+b)
so
Answer:

Step-by-step explanation:
We are given that velocity vector of a particle

When t=0 then the particle is at the point (0,-1,1).
We have to find the position of particle at time t.
We know that
Velocity =
Therefore,

Integrate on both sides then we get


Substitute the value of point at time t=0 then we get
C=
Substitute the value of C then we get

Therefore, the position of particle at time t
