Question

(х+y ) ( 2х - 3y) please solve this quick​

Answer 1

Step-by-step explanation:

value of m = - 1

Step-by-step explanation:

2x + 3y = 11 (1)

x - 2y = -12 (2)

Multiply (2) by 2 we get

2x - 4y = -24 (3)

subtract (3) from (1)

7y = 35

y=5

Put y= 5 in (1)

2x+15 =11

2x = 11-15

2x = -4

x = -2

Put the value of x and y in y = mx + 3

we get 5= - 2 m +3

or - 2m -2

or m = -1

teg me a brilliant

Answer 2

Step-by-step explanation:

Question :-

• (х+y ) ( 2х - 3y) please solve this quick

Given :-

• (х + y ) ( 2х - 3y)

Solution :-

= (х + y ) ( 2х - 3y)

= 2x² - 3xy + 2xy - 8y²

= 2x² - 8y² - xy

Hence the answer is 2x² - 8y² - xy
