Question

If a and b are thee roots of the equation x² + ax + b = 0, then find the least value of x² + ax + b (x<R).​

Answer 1

Step-by-step explanation:

Step-by-step explanation:(1)=>2a+b=0 and (2)=>a=1 or b=0. Thus we have x^+x-2=0 i.e (x+1/2)^2-9/4=0. Hence minimum value of x^2+ax+b=0 is -9/4.

I hope my answer is helpful for you .
