x^2 + x - p( p + 1)
We can write x as,
x = x + px - px
= x ( 1 + p) - px
= (p + 1)x - px
Now,
= x^2 + (p+1)x - px - p(p+1)
= x [ x + p +1] - p[ x + p + 1]
= (x + p + 1)(x - p)
We can write x as,
x = x + px - px
= x ( 1 + p) - px
= (p + 1)x - px
Now,
= x^2 + (p+1)x - px - p(p+1)
= x [ x + p +1] - p[ x + p + 1]
= (x + p + 1)(x - p)
I m not understanding your 2nd step
