Question

(v) (x + 2y) (-3x - y) - (x + y) (x - y) + (x - 2y) (2x + y) please give me solutions ​

Answer 1

Step-by-step explanation: (x + 2y) (-3x - y) - (x + y) (x - y) + (x - 2y) (-2x + y) = -3x²-xy-6xy-2y²-x²+y²-2x²+xy+4xy-2y² = -(6x²+2xy-3y²)

PLEASE MARK MY BRAINLIEST

Answer 2

Answer:

I can show you the simplification... don't know the solution though

Step-by-step explanation:

> (x + 2y) (-3x - y) - (x + y) (x - y) + (x - 2y) (2x + y)=0

> (-3x²-xy-6xy-2y²)-(x²-xy+x²-y²)+(2x²+xy-4xy-2y²)=0

> -3x²-2y²-xy-6xy-x²+xy-x²+y²+2x²+xy-4xy-2y²=0

> -3x²-3y²-9xy=0

> -3(x²+y²+3xy)=0

> x²+y²+3xy=0
