Determine the product of (2x^3y) and (3x^2y - 4xy^3)

Question

I need help on this problem for my weekly review. I have forgotten how to do algebra.

Answer 1

2x³y(3x²y) + 2x³y(-4xy³)

 

To start, remember that, say, a² = a(a) and a⁴ = a(a)(a)(a), so a²(a⁴) = a(a)(a)(a)(a)(a) = a⁶.

 

6x⁵y² - 8x⁴y⁴
