Let’s check out your problem:

Maya was asked whether the following equation is an identity:$\newline$$$(2 x+3)(x+1)=2(x+1)^{2}+(x+1)$$$\newline$She performed the following steps:$\newline$$$(2 x+3)(x+1)$$$\newline$$\stackrel{\text { Step } 1}{\hookrightarrow}=2 x^{2}+2 x+3 x+3$$\newline$$\stackrel{\text { Step } 2}{\hookrightarrow}=2 x^{2}+4 x+2+x+1$$\newline$$\stackrel{\text { Step } 3}{\hookrightarrow}=2\left(x^{2}+2 x+1\right)+(x+1)$$\newline$$\stackrel{\text { Step } 4}{\hookrightarrow}=2(x+1)^{2}+(x+1)$$\newline$For this reason, Maya stated that the equation is a true identity.$\newline$Is Maya correct? If not, in which step did she make a mistake?$\newline$Choose $1$ answer:$\newline$(A) Maya is correct.$\newline$(B) Maya is incorrect. She made a mistake in step $1$.$\newline$(C) Maya is incorrect. She made a mistake in step $2$ .$\newline$(D) Maya is incorrect. She made a mistake in step $4$.
