Question

If the quadratic equation x^2+4x+k=0 has real and distinct roots find the value of x

Answer 1

Hi ,

compare x² + 4x + k = 0 with ax² + bx + c = 0

a = 1 , b = 4 , c = k

it is given that roots are distinct and real ,

discreaminant ≥ 0

b² - 4ac ≥ 0

4² - 4 × 1 × k ≥ 0

- 4k ≥ - 16

4k ≤ 16

k ≤ 16/4

k ≤ 4

I hope this helps you.
