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

Factorise: 5a (2x -3y) + 2b (2x -3y)

What is the number of terms in the expansion of [(2x - 3y)^(2)(2x+3y)^(2)]^(2) ?

If (2x+3y+4) (2x+3y-5) is equal to (ax^(2)+by^(2) + 2hxy + 2gx +2fy +c) . Then what is the value of {3(g-f-c)//ab} ?

If (2x + 3y + 4) (2x + 3y -5) is equivalent to (ax^2 + by^2 + 2hxy + 2gx + 2fy + c) , then what is the value of (g+f-c) / (abh)

If a = (sqrt (2x + 3y) + sqrt (2x-3y)) / (sqrt (2x + 3y) -sqrt (2x-3y)) find the value of 3ya ^ (2) -4xa + 3y
