hello friends..
problem: simplify the following (2x-3y) (3x+y)+(x+2y) (x-y)
Solution:-
(2x-3y)(3x+y) + (x+2y)(x-y)
= (6x²+2xy-9xy-3y²) + (x²-xy+2xy-2y²)
= (6x² -7xy -3y²) + (x² +xy -2y²)
= 7x² -6xy - 5y²

Answer:
Step-by-step explanation:
(2x-3y) ( 3x+y) + ( x+2y) (x-y)
= 2x(3x+y) - 3y(3x+y) + x(x-y) + 2y (x-y)
= 6x+ 2xy - 9xy - 3y² + x² - xy + 2xy - 2y²
= 6x + 2xy + 2xy - 9xy -xy - 3y²-2y²
= 6x - 6xy - 5y²
