Answer 1

Объяснение:

1. a)14(1-m²)=14(1-m)(1+m)

b) 3a(1-a²)=3a(1-a)(1+a)

c) 3(x²-8xy+16y²)=3(x-4)²

d)-3a²(a²+4a+4)=-3a²(a+2)²

e)(a-b)²-25=(a-b-25)(a-b+25)

f)x(4+a)-y(4+a)=(x-y)(4+a)

g)x(x³+6)-8(x³+6)=(x-8)(x³+6)

2. a) (x+5)(b+c)

b) (4+a)(x-y)

c) (y-4)(x-b)

d) (x-8)(x³+6)

3. m²(a-b+2)+n(a-b+2)

(m²+n)(a-b+2)

4. 2(a²-2ab+b²)=2(a-b)²=2×49=98

5.9p²-24p+16-p²=8p²-24p+16=8(p²-3p+2)
