Объяснение:

(х+3)²=х²+6х+9

(4–у)²=16–8у+у²

(2m–5)²=4m²–20m+25

(7a+6b)²=49a²+84ab+36b²

(0,2x–10y)²=0,04x²–4xy+100y²

(a²–1)²=a⁴–2a+1

(x³–x²)²=(x^6)–2(x^5)+x⁴

(p²+p⁴)²=p⁴+2(p^6)+(p^8)

(–11b+2(a^5))²= 4(a^10)–44(a^5)b+121b²

(–8–4c)²=64+64c+16c²

(12xy²–x²y)²=144x²y⁴–24x³y³+x⁴y²

(4(a^6)+3a⁴b³)²=16(a^12)+24(a^10)b³+9(a^8)(b^6)
