Answer 1

Answer:

f(x)=x³+3x²+1

x=-1

f(-1)=-1³+3(-1)²+1

=-1+3+1

=3

f(x)=x³+3x²+1

x=1/2

f(1/2)=(1/2)³+3(1/2)²+1

=1/8+3(1/4)+1

=1/8+3/4+1

=1/8+6/8+8/8

=15/8

f(x)=x³+3x²+1

f=x

remainder is 1

f(x)=x³+3x²+1

f=-180

f(-180)=(-180)³+3(-180)²+1

=-5832000+3(32400)+1

=-5832000+97200+1

=-5734799

f(x)=x³+3x²+1

f=-5/2

f(-5/2)=(-5/2)³+3(-5/2)²+1

=-125/8+3(25/4)+1

=-125/8+75/4+1

=-125/8+150/8+8/8

=26/8

=13/4
