$3\left(x+1\right)^2+x$
Learn how to solve combining like terms problems step by step online. Reduce like terms 3(x+1)^2+x+1+-1. Subtract the values 1 and -1. 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 3 by each term of the polynomial \left(x^2+2x+1\right). Multiply 2 times 3.
