QUESTION:
Show that 2x _ 3 is a factor of p (x) = x+ 2xcube _ 9xsquare +12
ANSWER:
Q( x )=2x-3
P( x )=2x³-9x²+x+12
2x-3=0
=> 2x-3=0
=>2x=3
=>x=3/2
=>P( 3/2 ) =2(3/2)³-9(3/2)²+(3/2)+12
=2×27/8-9×9/4+3/2+12
=27/4-81/4+6/4+12
=(27-81+6+48)/4
=0/4
=0
AS THE REMAINDER BECOMES 0
SO THE Q(x) IS A FACTOR OF P(x)
