Question

One of the roots of the equation
x² +mx-5=0 is 2 find m
​

Answer 1

Answer:

m=1/2

Step-by-step explanation:

For the equation, x^2 + mx - 5 = 0 one of the roots is 2. So, 2 should satisfy the given equation.

Therefore,

Putting x=2 in the given equation,

(2)^2+2m-5=0

4+2m-5=0

2m-1=0

2m=1

m=1/2

Thus, the value of m is 1/2
