It is known that one root of the linear equation x & # 178; + 2x + M = 0 with respect to X is x = - 3 to find the value of M and the other root of the equation

It is known that one root of the linear equation x & # 178; + 2x + M = 0 with respect to X is x = - 3 to find the value of M and the other root of the equation

Taking x = - 3 into the equation, we get the following result:
9-6+m=0
The solution is m = - 3
So the equation is X & # 178; + 2x-3 = 0
That is: (x-1) (x + 3) = 0
The solution is x = 1 or x = - 3
So the other root of the equation is x = 1
