The answer for 2ab(xa^9+ya^3-6) is 2a^10bx + 2a^4by-6ab.
What is the mathematical expansion?
A mathematical expansion can be described as the finite combination of symbols which can be seen as one having rules which is usually based on the context that is been used.
The solution for the question is 2a^10bx + 2a^4by-6ab
Therefore, the expansion of 2ab(xa^9+ya^3-6) is 2a^10bx + 2a^4by-6ab.
