Multiply and put in simplest form:<br><br> 2x(4x+5) ANSWER= 8x^2+10x<br><br> Why is 8x squared?
Ksivusya [100]
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.)
