Answer 2

Heya !!

Here is ur answer

========================

Given quadratic equation :- k^2 + 4k +3

_______

Factorisation :-

Splitting the middle term

➡ K^2 + 4k +3 = 0

➡ K^2 + 3k + 1k +3. = 0

➡ 1k ( k + 3 ) + 1 ( k +3 ) = 0

➡ (K +3) ( 1k +1 ) = 0

Case (1)

➡ (K+3) =0

➡ K = -3

Case (2)

➡ (K+1) = 0

➡ K = -1

-----------------------

K = ( -1) , (-3)
