Question

.. Multiply (2x - 3y) by (9x + 4y).
​

Answer 1

Answer:

18x² - 12y² - 19xy

Step-by-step explanation:

(2x - 3y) × (9x + 4y)

= (2x×9x) + (2x×4y) - (3y×9x) - (3y×4y)

= 18x² + 8xy - 27xy - 12y²

= 18x² - 12y² - 19xy

Answer 2

Step-by-step explanation:

(2x*9x)+(2x*4y)-(3y*9x)-(3y*4y)

18x^2+8xy-27yx-12y^2

18x^2-19xy-12y^2
