#h^2+14h+49#

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#
