a^2+2ab+b^2

$\rightsquigarrow\circ\boldsymbol{Explanation}\circ\leftharpoonup$

Remember the rule for expanding a binomial squared.

$\twoheadrightarrow\sf (a+b)^2=a^2+2ab+b^2$

So we square the first term, then multiply the product of the two terms times 2.

$\twoheadrightarrow\sf a^2+2ab+b^2$

This is our answer.

Answer 2

Answer:

${a}^{2} + 2ab + {b}^{2}$

Step-by-step explanation:

$(a + b) {}^{2} = (a + b)(a + b) = {a}^{2} + ab + ab + {b}^{2} = {a}^{2} + 2ab + {b}^{2}$
