Question

how to divide x⁴+9x³+35x²-x+164 by x²+10x+41​

Answer 1

Answer:

Here is your answer mate

Step-by-step explanation:

Let's see..

x=−5+4i

Therefore,

x+5=4i

Square both sides to get,

(x+5)2=−16

Since i2=−1

x2+10x+25=−16

A little rearranging gives,

x2+10x+41=0 ….(I)

Try dividing

x4+9x3+35x2−x+4 by

x2+10x+41

The remainder comes out to be −160.

The answer, you should have realised by now, is −160 .
