h^2+14h+49

Explanation:

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

a^2 + 2ab + b^2 = (a+b)^2

In this case, solve the equation:
(h+7)^2

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

(h)^2 = h^2

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

h times 7 times 2 = 14h

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

(7)^2=49

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