Question

if the roots of the quadratic equation x2-4x-logN,then what is the minimum value of N?​

Answer 1

Answer:

Ask this in the Math section please.

Explanation:

Answer 2

Answer:

roots are real so

D>=0

minimum value,

D=0

so,b^2- 4ac=0

(-4) ^2-4*1*(-logN) =0

16+4logN=0

16=-4logN

-4=logN

N=10^-4

N=.0001
