Answer

$(5z+4)^{2}$

Work Step by Step

Given the polynomial $(5z)^{2}$ + 40z + $(4)^{2}$ We see that the polynomial has the first and last term squared and the middle term is +2 times the first and last term. Thus it follows the rule of $a^{2}$+2ab+$b^{2}$=$(a+b)^{2}$ In this polynomial a= 5z and b=4 $(5z)^{2}$ + 2(5z)(4) + $(4)^{2}$ = $(5z+4)^{2}$
