Question

one root of the equation x2+find x-5=0 is 2 . k

Answer 1

half

step by step:

For the equation, x² + mx − 5 = 0 one of the roots is 2. So, 2 should satisfy the given equation.

For the equation, x² + mx − 5 = 0 one of the roots is 2. So, 2 should satisfy the given equation.(2)² + m × (2) − 5 = 0

For the equation, x² + mx − 5 = 0 one of the roots is 2. So, 2 should satisfy the given equation.(2)² + m × (2) − 5 = 0⇒ 4+2m - 5 0 =

For the equation, x² + mx − 5 = 0 one of the roots is 2. So, 2 should satisfy the given equation.(2)² + m × (2) − 5 = 0⇒ 4+2m - 5 0 =⇒ 2m - 1 1

For the equation, x² + mx − 5 = 0 one of the roots is 2. So, 2 should satisfy the given equation.(2)² + m × (2) − 5 = 0⇒ 4+2m - 5 0 =⇒ 2m - 1 1m

For the equation, x² + mx − 5 = 0 one of the roots is 2. So, 2 should satisfy the given equation.(2)² + m × (2) − 5 = 0⇒ 4+2m - 5 0 =⇒ 2m - 1 1m2

For the equation, x² + mx − 5 = 0 one of the roots is 2. So, 2 should satisfy the given equation.(2)² + m × (2) − 5 = 0⇒ 4+2m - 5 0 =⇒ 2m - 1 1m2 Hence, the correct answer is half
