Question

2. Разложите многочлен на множители:
1) 2ах3 – 16ауз
2) y2 - 10y + 25 - 3xy + 15х
3) х2 + 2xy + y? + 2х + 2y +1
​

Answer 1

1) 2a(x³-8y³)= 2a(x-2y)*(x²+2xy+4y²)

2) (y-5)²-3x(y-5)= (y-5)*(y-5-3x)

3) (x+y)²+2(x+y)+1= (x+y+1)²= (x+y+1)(x+y+1)

Answer 2

1) 2a(x³-8y³)= 2a(x-2y)*(x²+2xy+4y²)

2) (y-5)²-3x(y-5)= (y-5)*(y-5-3x)

3) (x+y)²+2(x+y)+1= (x+y+1)²= (x+y+1)(x+y+1)
