1.Let f(x)=x2+ax+bf(x) = x^2 + ax + bf(x)=x2+ax+b, where a,b∈Ra, b \in \mathbb{R}a,b∈R. If f(x)=0f(x) = 0f(x)=0 has all its roots imaginary, then the roots of f(x)+f′(x)+f′′(x)=0f(x) + f'(x) + f''(x) = 0f(x)+f′(x)+f′′(x)=0 area.real and distinctb.imaginaryc.equald.rational and equalLogin to continueOnly logged in users canattempt or see the solution.
