Answer:
3,272
Step-by-step explanation:
8 x 400 = 3200
8 x 9= 72
3200 + 72 = 3,272
group the 1st 2 terms and last 2 terms:
(Z63 -2z^2) + (9z-18)
factor out GCF:
z^2(z-2) + 9(z-2)
now factor the polynomial:
(z-2) (z^2+9)
Answer:
1, 3, 7, 21
Step-by-step explanation:
1, 3, 7, 21
(The bolded is one factor and the other that is not bolded is another factor)
1 times 21 is 21
3 times 7 is 21
