Web24 nov. 2024 · (C) a,b and c are in H.P. As the roots of a(b-c)x^2+b(c-a)x+c(a-b)=0 are equal, the discriminant of the equation is 0 i.e. b^2(c-a)^2=4ac(b-c)(a-b) or b^2(c^2 … Web26 apr. 2024 · 4 Answers Sorted by: 1 Let one root be α then the other root will be α 2. Then, ( x − α) ( x − α 2) = 0 Note that you need a factorization of the form a ( x − α) ( x − α 2) = 0 to be able to compare with a x 2 + b x + c = 0. Alternatively, you can divide by a and continue with a quadratic where a = 1. Other than that, the approach is fine.
