## Step-by-step Solution

Problem to solve:

$\left(x+2\right)^2$
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: $(a+b)^2=a^2+2ab+b^2$

• Square of the first term: $\left(x\right)^2 = x^2$
• Double product of the first by the second: $2\left(x\right)\left(2\right) = 2\cdot 2x$
• Square of the second term: $\left(2\right)^2 = 2^2$

$x^2+2\cdot 2x+2^2$

$x^2+2\cdot 2x+2^2$

Learn how to solve special products problems step by step online. Expand the expression (x+2)^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<ul><li>Square of the first term: \left(x\right)^2 = x^2</li><li>Double product of the first by the second: 2\left(x\right)\left(2\right) = 2\cdot 2x</li><li>Square of the second term: \left(2\right)^2 = 2^2</li></ul>. Multiply 2 times 2. Calculate the power 2^2.
