Any vector that is a multiple of (3, 1) will be orthogonal. These include
.. A (-6, -2)
.. D (3, 1)
_____
The dot-product of these with (-1, 3) is zero:
(-6*-1 +-2*3) = 6 -6 = 0
(3*-1 +1*3) = -3 +3 = 0
You can make a vector orthogonal to a 2-D vector by swapping the coordinates and negating one of them. When you swap the elements of (-1, 3) you get (3, -1). It is usually convenient to negate the one that is already negative, so that would give you (3, 1) as the orthogonal vector.

Answer:
The polynomial is 
Step-by-step explanation:
∵ The polynomial of dgree 4 has 3 , 1 and zero as a double root
∴ x = 3 , x = 1 , x = 0 , x = 0
∴ The factors of this polynomials are:
(x - 3) , (x - 1) , (x) , (x)
∴The polynomial = (x)(x)(x - 3) (x - 1)
∴ The polynomial =
