Question

Help with question pls I don't understand​

Answer 1

15
`x^(3)`y + 6
`x^(2)`
`y^(2)` + 9x
`y^(3)`

Explanation:

multiple everything in the brackets by 3xy

3xy x 5
`x^(2)` = 15
`x^(3)`y

3xy x 2xy = 6
`x^(2)`
`y^(2)`

3xy x 3
`y^(2)` = 9x
`y^(3)`

15
`x^(3)`y + 6
`x^(2)`
`y^(2)` + 9x
`y^(3)`

Answer 2

15x^3y+6x^2y^2+9xy^3

Explanation:

3xy ( 5x^2 +2xy +3y^2)

Distribute the 3xy to all terms in the parentheses

3xy*5x^2+3xy*2xy+3xy*3y^2

15x^3y+6x^2y^2+9xy^3
