Question

Fill in the blank to make the expression a perfect square.
v^2-6v+?

Answer 1

\[v(v^2/v+−6v/v)\]
simplify each term in parentheses:
\[v(v-6)\]

Answer 2

can you explain further? @AnitaS.

Answer 3

Hey Kelly :)
\(\large\rm v^2\color{orangered}{-6v}\quad=v^2\color{orangered}{-3v-3v}\)

If you split the middle term in half like this,
you can determine that the missing piece that we need is (-3)*(-3)

Answer 4

It actually told me the answer was 9.

Answer 5

@KellyRJr yes, -3*-3 = 9
sorry if you didn't understand that.
