Question

ON DIVIDING x² + 3x² + 3x + 1 BY 2x+5
WE GET REMAINDER​

Answer 1

Step-by-step explanation:

Let f(x)=x²+3x²+3x+1 = 4x²+3x+1

Since,

2x+5=0 =》x= -(5/2)

By Remainder Theorem:

We get:

f(-5/2)=4×(25/4)+3×(-5/2)+1

=》f(-5/2)=25+-15/2+1

=》f(-5/2)=26+(-15/2)

=》f(-5/2)=(37/2)

Hence,Remainder =(37/2)
