could someone help me with math?

Question

Multiply the following by applying the distributive property.

3x^2y(5x^3y-2x^2y2^+3y^3)

Answer 1

Hello, Seth,

 

The original expression has the form a·(b+c+d) where a=3x², b=5x³y, c=^-2x²y² and d=3y³.

Use the distributive property a·(b+c+d)=a·b+a·c+a·d, which in this case gives 3x²·5x³y+3x²·^-2x²y²+3x²·3y³=15x⁵y+^-6x⁴y²+9x²y³.
