Answer 1

Объяснение:

a) m²–4+7m²(m–2)= (m–2)(m+2)+7m²(m–2)= (m–2)(m+2+7m²)

b) n²–8n+16–5n²(n–4)= (n–4)²–5n²(n–4)= (n–4)(n–4–5n²)

c) –5p²+60p–180+6p²(p–6)= –5(p²–12p+36)+6p²(p–6)= –5(p–6)²+6p²(p–6)= (p–6)(–5(p–6)+6p²)= (p–6)(–5p+30+6p²)

d) 2m²+16m+32+9m(m+4)²= 2(m²+8m+16)+9m(m+4)²= 2(m+4)²+9m(m+4)²= (m+4)²(2+9m)
