the total of 3 times the cube of u and the square of u
The cube of u means we raise u to the power of 3:
u^3
The square of u means we raise u to the power of 2:
u^2
The total of both of these is found by adding them together:
u^3 + u^2
The cube of u means we raise u to the power of 3:
u^3
The square of u means we raise u to the power of 2:
u^2
The total of both of these is found by adding them together:
u^3 + u^2
