First we should split the middle term

By the video... you should have understood that we need to make 3x in two number that one is divisible by 2 and the other is divisible itself

x2+x+2x+2x21

You should always remember that
1=12
It'll always help you

Factorize
x(x+1)+2(x+1)x212

It is a law of exponents
a2b2=(a+b)(ab)

(x+2)(x+1)(x1)(x+1)

You are left with
x+2x1
