ok @ShawnSpencer thanks anyways

anonymous · Answer

i know what you mean i like to learn it

anonymous · Answer

i dont like learning its just that its something i need to learn for the ECA

$v^2 + 10v + 16 = (v + 8)(v +~?)$

Okay, it wants you to find the number and then you multiply the two binomials together..and we have to get $v^2 + 10v + 16$ when we do.

Let's try 2 first:

$v^2 + 10v + 16 = (v + 8)(v + 2)$

$(v + 8)(v + 2)$

Distribute, when we distribute we multiply the first term in the first parenthesis to both numbers in the last parenthesis, and then we multiply the 2nd term in the first parenthesis to both numbers in the last parenthesis, so we're going to multiply:

$v \times v$

$v \times 2$

$8 \times v$

$8 \times 2$

Can you multiply those?

anonymous · Answer

v^2
v2/2v
8v
16

anonymous · Answer

Yes!

So we have:

$v^2 + 2v + 8v + 16$

Now we combine like terms, we add $2v + 8v$, and what do you get?

anonymous · Answer

10v

anonymous · Answer

Yes, so we get:

$v^2 + 10v + 16$

So 2 is our answer! Because when we plug it in and distribute we get $v^2 + 10v + 16$.

$v^2 + 10v + 16 = (v + 8)(v + 2)$
