Question
From 
subtract 
Hint:
We are given two equations. We have to perform operation between them.
The correct answer is:
The given equations are as follows:
x3 - 3x2 + x ...(1)
-x3 +3x2 - x ...(2)
We have to subtract (2) from (1)
x3 - 3x2 + x - ( -x3 + 3x2 - x) = x3 - 3x2 + x + x3 - 3x2 + x
= x3 + x3 - 3x2 - 3x2 + x + x
= 2x3 - 6x2 + 2x
We took the like terms together means terms having same variable and power together and performed operation between them.
The final answer is 2x3 -6x2 + 2x
For such questions, we should know the concept of like and unlike terms.

A force F = –K(yi + xj) (where K is a positive constant) acts on a particle moving in the xy–plane. Starting from the origin, the particle is taken along the positive x–axis to the point (a, 0) and then parallel to the y–axis to the point (a, a). The total work done by the force F on the particles is:
