Question

(X+Y) (2X+3Y) - (X+Y) (X+1)​

Answer 1

Возможно так, точно не уверен.

Answer 2

To simplify the expression (X+Y)(2X+3Y) - (X+Y)(X+1), you can use the distributive property to factor out (X+Y) from both terms:

(X+Y)(2X+3Y) - (X+Y)(X+1) = (X+Y)[(2X+3Y) - (X+1)]

Now, expand the expression inside the square brackets:

(2X+3Y) - (X+1) = 2X + 3Y - X - 1

Combine like terms:

(2X - X) + (3Y - 1) = X + (3Y - 1)

So, the simplified expression is:

X + 3Y - 1
