a) b^2+11b+80R276
b) b^2-11b+38R140
c) b^2-3b+18
d) b^2-3b+18R252

Answer 1

b^2 - 3b + 18 R 2.

Explanation:

Using long division:

b^2 - 3b + 18 <----------------Quotient.

----------------------------------

b + 7 ) b^3 + 4 b^2 - 3b + 128

b^3 + 7b^2

-3 b^2 - 3b

-3 b^2 -21b

18b + 128

18b + 126

2 <--------- remainder.
