Question

This is an standard result for 2 quadratic eqn to have common root. How is this derived, explain in detail.

Answer 1

Answer:

The subject in a simple English sentence such as John runs, John is a teacher, or John was run over by a car, is the person or thing about whom the statement is made, in this case John. Traditionally the subject is the word or phrase which controls the verb in the clause, that is to say with which the verb agrees.

Answer 2

Answer:

(c1a2 - c2a1)^2 = (b1c2 - b2c1)(a1b2 - a2b1), which is the required condition for one root to be common of two quadratic equations. Note: (i) We can find the common root by making the same coefficient of x^2 of the given equations and then subtracting the two equations
