Explanation:

Hey, there!

Let me simply clear you.

While multiplying algebraic expression, you must be very careful about sign and brackets.

Here,


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

Let's multiply (x-2y) by (x+3y)


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


= ({x}^(2) - 2xy) + (3xy - 6 {y}^(2))

Open brackets.


= {x}^(2) - 2xy + 3xy - 6 {y}^(2)

Simplify the like terms.


= {x}^(2) + xy - 6 {y}^(2)

Therefore, the answer is x^2 + xy- 6y^2.

Hope it helps.....

Answer:

x² + xy - 6y²

Explanation:

FOIL

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

F= x²

O= -2xy

I= 3xy

L= -6y²

Add these together = x² + xy - 6y²
