Question
In Exercises $45-66,$ factor any perfect square trinomials, or state that the polynomial is prime.$$x^{2}+16 x y+64 y^{2}$$
Step 1
A perfect square trinomial is of the form $(a+b)^2 = a^2 + 2ab + b^2$. In this case, $x^2$ is the square of $x$, $64y^2$ is the square of $8y$, and $16xy$ is twice the product of $x$ and $8y$. Show more…
