Answer
The statement $(x+1)^2=x^2+1$ is false.
The correct statement is $(x+1)^2=x^2+2x+1$.
Work Step by Step
The square of a binomial can be found using the formula $(a+b)^2=a^2+2ab+b^2$. The square of the sum of two terms is NOT the sum of the square of each term.. $$(x+1)^2=x^2+2(x)(1)+1^2$$ $$=x^2+2x+1$$ The statement$(x+1)^2=x^2+1$ is false because the second term is missing.
The correct statement is $(x+1)^2=x^2+2x+1$.
