Question

Multiply the following by applying the distributive property.

3x2y(5x³y-2x²y2+3y³)

Answer 1

That's a monomial standing outside the parenthesized group.  It should be multiplied by each term within the parentheses, one after another.  I ASSUME THAT THIS MONOMIAL SHOULD BE "3x squared times y"

 

Distributing the monomial onto the first term within parentheses, you get all of these factors, multiplying:

3   xx   y   5  x x x  y    which should become 15 x⁵y²

 

Next, you'd get all of these factors, multiplying, including a - sign:

- 3 xx y 2 xx yy   HERE I ASSUME THAT THE MIDDLE TERM (within parentheses) HAS A Y SQUARED FACTOR

which should become -6x⁴y³

 

Get the idea?? 

 

NOTE: PLEASE BE CAREFUL WHEN KEYING IN EXPRESSIONS--make sure that exponents are "RAISED" & also take care with parentheses to control proper order of operations. Mistakes in format really louse up the readability!
