Question

1x (x + y) (2x + 3y) – (x + y) (x + 1),​

Answer 1

Answer:

2x³ + 5x²y + 3xy²− x² − xy− x − y

Step-by-Step Explanation:

Let's simplify step-by-step.

1x (x + y) (2x + 3y) - (x + y) (x + 1)

Distribute:

= (1x(x + y))(2x) + (1x(x + y))( 3y) + - x² - + - xy + - x + - y  

= 2x³ + 2x²y + 3x²y + 3xy² + - x² + - xy + - x + - y

Combine Like Terms:

= 2x³ + 2x²y + 3x²y+ 3xy² + -x² + -xy + -x + -y

= (2x³) + (2x²y + 3x²y) + (3xy²) + (-x²) + (-xy) + (-x) + (-y)

= 2x³ + 5x²y + 3xy²− x² − xy− x − y

 

Answer:

 

= 2x³ + 5x²y + 3xy²− x² − xy− x − y
