SOLUTION: (3-z)(4z^3+6x+2)= (4z^3+6x+2) ganna be (64z+6x+2) ok now 6x+2= 8x+64z= 72xz. now 3-z = 3-1 coz x=-1 and it's = 2 X 72xz= 144xz

Question 151945:
(3-z)(4z^3+6x+2)= (4z^3+6x+2) ganna be (64z+6x+2) ok now 6x+2= 8x+64z= 72xz.
now 3-z = 3-1 coz x=-1 and it's = 2 X 72xz= 144xz

(3-z)(4z^3+6x+2)= (4z^3+6x+2) ganna be (64z+6x+2) ok now 6x+2= 8x+64z= 72xz.
now 3-z = 3-1 coz x=-1 and it's = 2 X 72xz= 144xz..
my answer is 144xz
