${h}^{2} + 14 h + 49$

#### Explanation:

Typically, the way for multiplying squared binomials with a positive sign is by using this equation:

${a}^{2} + 2 a b + {b}^{2}$ = ${\left(a + b\right)}^{2}$

In this case, solve the equation:
${\left(h + 7\right)}^{2}$

The first part would be squaring the first term, which is $h$ in this equation.

${\left(h\right)}^{2} = {h}^{2}$

Second part is finding the product of the two terms given, then times two:

$h \times 7 \times 2 = 14 h$

Third part is squaring the second term, which is $7$ in this equation:

${\left(7\right)}^{2} = 49$

Combine it together and you would get ${h}^{2} + 14 h + 49$
