Question

7x^3y-14x^2 y^2+21xy^3​

Answer 1

Answer:

• 14x2 + 11xy- 15y2 = 14x2 + 21xy – 10xy – 15y2. = 2x (7x – 5y) + 3y (7x – 5y). = (2x + 3y) (7x ... So, we write the middle term -5(x – 2y) as -2(x – 2y) -3(x – 2y).

Answer 2

Answer:

14x2 + 11xy- 15y2 = 14x2 + 21xy – 10xy – 15y2. = 2x (7x – 5y) + 3y (7x – 5y). = (2x + 3y) (7x ... So, we write the middle term -5(x – 2y) as -2(x – 2y) -3(x – 2y).
