If a, b, c are natural numbers and they satisfy the condition that root number a-2 root number 6 is equal to root number b-root number c, find the value of a
A-2 root 6 under root equals root b-root c,
The square of both sides of the equation, then
A-2 root 6= b+c-2 root bc
In order for the equation to hold, it is obvious that bc=6, so b and c are taken as 2,3 or 3,2, and substituted in, a=5.
A-2 root 6 under root equals root b-root c,
The square of both sides of the equation, then
A-2 root 6= b+c-2 root bc
In order for the equation to be true, it is clear that bc =6, so b, c take the value of 2,3 or 3,2, substitute, a =5.
