Final answer to the problem
Step-by-step Solution
Specify the solving method
A binomial squared (sum) is equal to the square of the first term, plus the double product of the first by the second, plus the square of the second term. In other words: $(a+b)^2=a^2+2ab+b^2$

$esx\left(x^2+2x+1\right)$
Learn how to solve special products problems step by step online. Expand the expression esx(x+1)^2. A binomial squared (sum) is equal to the square of the first term, plus the double product of the first by the second, plus the square of the second term. In other words: (a+b)^2=a^2+2ab+b^2. Multiply the single term esx by each term of the polynomial \left(x^2+2x+1\right). When multiplying exponents with same base you can add the exponents: ex^2sx. When multiplying two powers that have the same base (x), you can add the exponents.
