Question

Find the remainder when x3+3x2+3x+1 is divided by 2x+5

Answer 1

Answer:

Divinding x³+3x²+3x+1 by 2x+5

Step-by-step explanation:

Put,

Divisor=0

2x+5=0

2x= -5

x= -5/2

Now,

Let p(x)= x³+3x²+3x+1

Put the value of x = -5/2

p(-5/2)=(-5/2)³+3(-5/2)²+3(-5/2)+1

=(-125/8)+(75/4)-15/2+1

Taking lcm,

=( -125+150-60+8)/8

= -27/8 Ans!!
