Answer :
Squaring a number is the same as multiplying the number by itself (64⋅64). In this case, 64 squared is 4096.
8r^3−4096+r−8
Subtract 8 from −4096 to get −4104.
8r^3−4104+r
Factor the polynomial using the rational roots theorem.
(r−8)(8r^2+64r+513)
8r^3−4096+r−8
Subtract 8 from −4096 to get −4104.
8r^3−4104+r
Factor the polynomial using the rational roots theorem.
(r−8)(8r^2+64r+513)
