it is very easy . we can split middle term easily .you just have to focus on this example.
eg . 2x² + 2x + 2
a =2 , b=2 , c=2
☆ a×b = 2×2=4 , this means last term (c) is 4 . if in a =1 then there will be no change in the last term if except 1 any number is given as a we have to multiple woth last term (c) .
☆ now focus on middle part. how we can get 2 in the middle if last term is 4.
☆ if we [ 4 -2=2 ]
that means it can be 4x-2x
writeitnow,finalresultwillbe:
2x²+4x-2x+2=0
( take 2x as common becose in both terms there is 2 and x )
2x ( x+2) - 2(x+2) =0
(2x-2) (x+2) =0
2x-2 = 0 x+2=0
2x =2 x=-2
x=2/2=1
hence, x= 1 and -2 . (negative value is not taken )

write it now , final result will be :
2x² +4x - 2x +2 =0
( take 2x as common becose in both terms there is 2 and x )
2x ( x+2) - 2(x+2) =0
(2x-2) (x+2) =0
2x-2 = 0 x+2=0
2x =2 x=-2
x=2/2=1
hence, x= 1 and -2 . (negative value is not taken )
so the real value of x is 1.
