Question

Find the value of K, which one root of the quadratic equation kx^2-14x+8=0 is 2.

Answer 1

Answer:

k = 5

Step-by-step explanation:

∵ 2 is one of the root of qiven quadratic equation we can say x =2

Putting value of x in kx² - 14x + 8 = 0

k(2)²- 14(2) + 8 = 0

4k - 28 + 8 = 0

4k - 20 = 0

4k = 20

k = 5
