Question

Expand and simplify.
2x(x + 4)

Answer 1

Answer: 2xsquared + 8x (sorry i cant do the squared symbol on my phone)

Explanation : you need to multiply out the brackets so if you have 2 xs and you are multiply with brackets they then become x squared as there is 2 of them. You get 8x as when you times 2 by 4 you get 8 and as you already have an x there it would have to be 8x. Hope this helps!

Answer 2

Hello there! 2x² + 8x.

2x(x + 4) > start by multiplying 2x by both terms in the equation.

so, 2x(x + 4) is the same as 2x(x) + 2x(4).

We are left with 2x² + 8x.

We cannot simplify this anymore, so this is your final answer. :)
