fill in the blank to make the expression a perfect square v^2-16v+
where is the aaaaaaaaaaaaaaannnnnnnnnnnnnnnnsssssssssssswwwwwwwwwwwweeeeeeerrrrrrrrrrr
I’m literally over 7 years late but the answer is 64, I hope I helped with your homework :)
64
To make the expression v^2 - 16v + _____ a perfect square, you'll need to add a term that completes the square.
In this case, we can calculate the term by taking half of the coefficient of the linear term (in this case, -16), and then squaring it.
Half of -16 is -8, and when squared, it becomes 64.
So, the expression v^2 - 16v + 64 is a perfect square.
(x+a)^2 = x^2 + 2ax + a^2
So, it looks like 2a = -16
that makes a^2 = ?
