Answer 1

(1+x)²=1+2x+x²

(-m-10)²=m²+20m+10

(10t+3t)²=100t²+60t²+9t²=169t²

(8p³+5p²g)²=64p^5+80p^5g+25p⁴g²

(10c+0,1y)²=100c²+2cy+0,01y²

(y-2)²=y²-4y+4

(-x+1)²=(1-x)²=1-2x+x²

(6a-1/6в)²=36a²-2aв+1/36в²

(-3a+5x)²=(5x-3a)²=25x²-30ax+9a²

(6a²-0.5aв)² = 36а⁴-6а³в+0,25а²в²

(3в-1)(3в+1)=9в²-1

(х+7)(7-х)=7х-х²+49-7х=-х²+49

(4а-в)(в+4а)=4ав+16а²-в²-4ав=16а²-в²
