Question

(wx - y)2
but it have to b put on a grid like polynomials

espex · Answer

Do you have to expand this expression?

anonymous · Answer

yes

espex · Answer

All you need to do is to FOIL the expression times itself: $$(wx-y)(wx-y)$$

anonymous · Answer

like I have to put them an a box n order

espex · Answer

I'm not sure I understand what you're needing to do, can you explain a little more or give me an example?

anonymous · Answer

sure
(x + y)(x - y)  answer is x squared y squared

anonymous · Answer

(0.1x + 0.4y)2

espex · Answer

Okay, so you will just do that exact same thing with this problem.
If it helps, think of wx as a single 'x'.

espex · Answer

Again, the same process, you are squaring the whole (0.1x+0.4y), so you will have it multiplied by itself.

anonymous · Answer

is there a number I can reach yuh at

espex · Answer

No, but there is the thread we're working in. :)

anonymous · Answer

okay what about this (2x -1 over two )2

espex · Answer

If we are assuming that this is an exercise in expansion, you will do the same with this problem. $$(2x-\frac{1}{2})(2x-\frac{1}{2})$$ Simply FOIL the terms to expand your factors.

anonymous · Answer

(x + 2)(x - 2)

espex · Answer

$(a+b)(a-b) = (a^2-b^2)$
