Question

if 2x+1 is one factor of the polynomial 2xsquare -x-1,then find the other factors​

Answer 1

By applying spiltmethod we solve it.

2x^2 - x - 1

2x^2 + x - 2x - 1

x (2x + 1 ) -1 ( 2x + 1 )

( x - 1 ) (2x + 1 )

Now we divide it.

( x - 1 ) ( 2x + 1 ) / ( 2x + 1 )

Other factors is ( x - 1 ).

This is the answer of your question. I hope that it will help you.
