1)1.69(14)-1.21 = (1,3(7) - 1,1)(1,3(7) + 1,1)2)a(2)-0.01 = (a-0,1)(а+0,1)
3)3p+2pc = р(3 + 2с)
4)a(2)b(2)-4ab(3)+6(3)b = b(a(2)b - 4ab(2) + 6(3))
5)3a(2)6a(3)+18(4)=18(a(6) + 18(3)) = 18(a(2) +18)(a(4) + 18a(2) + 18(2))
6)3y(2x-9)-5(2x-9) = (2x - 9)(3y - 5)
7)2p(a-x)-p(x+a) = p(3a - x)
8)ax-ay+bx+by = не знаю
9)5x(2)-45 = 5(х-3)(х+3)
10)5a(2)+10ab+5b(2) = 5(a+b)(2)
11)2ax+3by+6ay+bx = (2a + b)(x+3y)
