HW help plz
Squaring a binomial can be compared to finding the area of a square. Multiply the length of the side by itself. For example:
(a + b)^2 = a^2 + 2ab + b^2 or (ab)^2 = a^2 + 2ab  b^2
Problem: The areas of four squares are listed below. Find the length of the side. Then find the perimeter.
(a) a^2 + 8a + 16
(b) a^2 10a + 25
(c) 49a^2 56a + 16
(d) 36a^4 12a^2b^3 + b^6
