Question

if one root of the quadratic equation x^2-7k+k=0 is x=2 find the value of k​

Answer 1

Answer:

If one root of the quadratic equations is 2value of k

Answer 2

Given:-

• one root of the quadratic equation x² − 7x + k = 0 is 2.

To Find:-

• Value of K = ?

Explanation:-

∴ Substituting x = 2 in the given equation, we have

x² − 7x + k = 0 is 2.

➩ x² − 7x + k = 0

➩ (2)² − 7(2) + k = 0

➩ 4 − 14 + k = 0

➩ −10 + k = 0
