Answer:
(3y³x + 9x²y-2y²-4x)
Step-by-step explanation:
The given expression is ( 9x²y - 4x + 3y³x - 2y² )
To write this expression in a standard form we will arrange each term as the reducing degree of each term.
Degree of 9x²y = degree of x + degree of y
= 2 + 1
= 3
Similarly degree of 4x = 1
degree of 3y³x = 3+1 = 4
degree of 2y² = 2
Now we arrange the terms.
(3y³x + 9x²y-2y²-4x)
