Question

if m>0, n>0 and p>0, then both the roots of the equation mx²+nx+p=0 are

• A. real and negative
• B. have –ve real parts
• C. rational numbers
• D. cannot be determined
• E. none of these

Answer 1

The correct option is B have –ve real parts

option (b)

x=(-b±√D)/2a

D=n²-4mp<n² (as m>0 and p>0), the roots of this equation will be –ve. If D<0, then the roots will have negative real parts
