Question

(x + 1) (x+2)
x² + x +1​

Answer 1

(x+1)(x+2)

= x(x+2)+1(x+2)

=x²+2x+x+2

=x²+3x+2

Answer 2

Answer: x=-0.5

Step-by-step explanation:

The given question is wrong.

I think the question may be-- (x + 1) (x+2) =x² + x +1​,Find the value of x ?

(x + 1) (x+2) =x² + x +1​

or,x²+x+2x+2=x² + x +1​

or,x²+3x+2=x² + x +1​

or,3x-x=1-2

or,2x=-1

or,x=$\frac{-1}{2}$=-0.5
