Question

Multiply and put in simplest form:

2x(4x+5) ANSWER= 8x^2+10x

Why is 8x squared?

Answer 1

Because you're multiplying
`2x` by
`4x`.
`2*4` is
`8`,
`x*x` is
`x^2[tex], and [tex]8*x^2` is
`8^2`. Since you're multiplying them all together, it doesn't matter what order you multiply them in. For example,
`2*x=2x`,
`x*4=4x`, and [2x*4x=8x^2[/tex] (but that's just the same.)

Hope that helps! :)
