Wow.... impressive
Can we solve it by using Rational root theorem?
Sir, it's all okay but we are dividing by x+2 so we need to prove x cannot be -2. Which is easy to prove because if x=-2 then x^2+bx+2b-1=0 implies 4-2b+2b-1=0 implies 3=0 which is impossible thus x cannot be -2 thus we can divide by x+2.
Sir Csir net june 2025 ka batch kab start hoga (Regular classes)
