looking at the coefficient of on the left hand side of the equation:
So ........................(1)
Now look at the cofactors of x:
So ......................(2)
Now look at the constant terms: ..............................(3)
Looking at equation (1), since thwe number 2 is a prime number, there are only two numbers that "a" and "c" could be: 1 and 2.
Let a=2 and c=1.
Looking at equation (3), since thwe number 3 is a prime number, there are only two numbers that "b" and "d" could be: 1 and 3. This time we need to make sure that we get these two numbers the right way round, so we check with equation (2):
so if b and d can omly be 1 or 2, the only the above equation works is if b=1 and d=3.
Put the values of a, b, c and d into the equation at the very top:
I hope this helps.
