let f(x) = k( x-2)(x-3) + ax+b
put x= 2
f(2) = 2a + b = 1
put x= 3
f(3) = 3a +b =3
subtract both
2a -3a = 1 -3
-a = -2
a= 2
put in 2a +b = 1
b = 1-2a = -3
remainder = ax +b = 2x-3
put x= 2
f(2) = 2a + b = 1
put x= 3
f(3) = 3a +b =3
subtract both
2a -3a = 1 -3
-a = -2
a= 2
put in 2a +b = 1
b = 1-2a = -3
