Solution:- let we take standard form of quadratic polynomials means,
P(x)=ax^2+bx+c
Follow some rule for factorisation :-
- Here we first multiple constant term c and cofficient of x^2 , means c×1=c
- Again do prime factorisation of c,means c=c×1, example:- prime factorisation of 20=2×2×5
- Again, For example c has sign +ve means middle term is completed by add and c has sign -ve means middle term is completed by subtracte
