Question

determine whether the given value of m are root of the q.e or not m2+3=0,m=-1,2

Answer 1

To checkwhether the given value of m are root of the eq or not
Put m=-1 in given eq:
m2+3=(-1)^2+3=4

Now put m= 2 in given eq :
m2+3= 4+3=7

As we didn't for zero after replacing m in eq means m=-1 and 2 are not solution. Of equation.
