Question

please solve the above question ​

Answer 1

Answer:

assume a polynomial,

f(x)= x+2x³-9x²+12

2x-3=0

or, x=3/2

now,

f(3/2)=(3/2)+2(3/2)³+-9(3/2)²+12

=0

from remainder theorom we get, if f(a) =0 then (x-a) , is a factor of f(x)

as , f(3/2)=0 is proved , hence (2x-3) is a factor of f(x)
