We will use distributive law to find product in each case.

	First expression	Second expression	Product
(i)	$a$	$b+c+d$	$ab + ac+ ad$
(ii)	$x+y-5$	$5xy$	$5x^2y + 5xy^2 - 25xy$
(iii)	$p$	$6p^2-7p+5$	$6p^3 - 7p^2 + 5p$
(iv)	$4p^2q^2$	$p^2-q^2$	$4p^4q^2 - 4p^2q^4$
(v)	$a+b+c$	$abc$	$a^2bc + ab^2c + abc^2$
