Question

Multiply each of the following(2x - 3y) and (x + 5y)​

Answer 1

Answer:

$2 {x}^{2} + 7xy - 15 {y}^{2}$

Step-by-step explanation:

We can use the rainbow expansion method to find the expression.

$(2x - 3y)(x + 5y) \\ = 2 {x}^{2} + 10xy - 3xy - 15 {y}^{2} \\ = 2 {x}^{2} + 7xy - 15 {y}^{2}$
