x(x-4)(x-1)
________
2(x+4)
Proof by contadiction.
Let assume there exist such positive integers and whose sum is a prime number , that their greatest common divisor is greater than 1.
Since is a prime number and , then , but we assumed earlier that , and there are no two positive integers that sum up to 1.
q.e.d.
n=0
Clear parenthesis w/ distribution:
3(-7n+1)=-21n+3
Move everything over to one side:
6n+3=-21n+3
6n=21n Subtract the 3 on the right.
-15n=0 Subtract the 21.
n=0 Divide the -15.
