yellok (2m-0.7)(2m+0.7)=(2m)²-0.7²=4m²-0.49
(1.2-5y)(1.2+5y)=1.2²-(5y)²=1.44-25y²
(8n+0.6)(8n-0.6)=(8n)²-0.6²=64n²-0.36
(0.9p+2)(0.9p-2)=(0.9p)²-2²=0.81p²-4
(1.1d-8)(8+1.1d)=(1.1d)²-8²=1.21d²-64
(0.1a+1)(1-0.1a)=1²-(0.1a)²=1-0.01a²

dmitrij330 (2м-0,7) (2м+0,7) = 4м²-0,49
(1,2-5у) (1,2+5у) = 1,44 - 25у²
(8н+0,6) (8н-0,6) = 64н² - 0,36
(0,9р+2) (0,9р-2) = 0,81р²-4
(1,1д-8) (8+1,1д) = (1,1д-8) (1,1д+8) = 1,21д²-64
(0,1а+1) (1-0,1а) = (1+0,1а) (1-0,1а) = 1 - 0,01а²
