Question

Помогите пожалуйста,очень надо!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

1)y^6×(1-y)(1+y)

3)c(c^2-1)+5(c^2-1)=0
(c+5)(c^2-1)=0
(c+5)(c-1)(c+1)=0

c=-5
c=1
c=-1

4)(8x-1)(64x^2+8x+1)

5)81y-y^2=0
-y^2+81y=0
y^2-81y=0
a=1; b=-81; c=0
D=b^2-4ac=6561-4×1×0=6561

y1,2=-b^2+-√D/2a

y1=81+81/2=81
y2=81-81/2=0
