simplify (2sqrt(x)+sqrt(y))(3sqrt(x)-5sqrt(y))

simplify

(2 x + y) (3 x - 5 y)

6 x - 7 x y - 5 y

Solution steps

(2 x + y) (3 x - 5 y)

Expand

(2 x + y) (3 x - 5 y) : 6 x - 10 x y + 3 y x - 5 y

= 6 x - 10 x y + 3 y x - 5 y

Add similar elements:

- 10 x y + 3 x y = - 7 x y

= 6 x - 7 x y - 5 y
