Объяснение:

1) (a-b) ²-5²=(a-b-5) *(a-b+5)

3) x²-(16b²-8bc+c²) =x²-(4b-c) ²=

(x-(4b-c)) *(x+(4b-c)) =(x-4b+c)*(x+4b-c)

5) (b⁵)²-(5²(b⁴)²+2*5*b⁴*4+4²) =

(b⁵)²-(5b⁴+4)²=(b⁵-(5b⁴+4))*(b⁵+(5b⁴+4)) =

(b⁵-5b⁴-4)*(b⁵+5b⁴+4)

7) (2x-3y) ²-(2a-b) ²=

(2x-3y-(2a-b)) *(2x-3y+(2a-b)) =

(2x-3y-2a+b) *(2x-3y+2a-b)
