${y}^{2} + 12y + 20$

$\large \colorbox {pink}{step by step explanation}$

simplify

1. distribute

$(y + 2)(y + 10)$

$y(y + 10) + 2 \: (y + 10)$

2. distribute

$y(y + 10) + 2(y + 10)$

${y}^{2} + 10y + 2(y + 10)$

3. distribute

${y}^{2} + 10y + 2(y + 10)$

${y}^{2} + 10y + 2y + 20$

4. combine like terms

${y}^{2} + 10y + 2y + 20$

${y}^{2} + 12y + 20$
