assuming that x isnt equal to 1/2 simplify 8x^2 - 4x / 4x - 2

Wouldn't that just be **2x**

Maybe I'm wrong but I'm visualizing that (2x)(4x – 2) = 8x^{2} – 4x

Okay, I see what the first guest did.

I assumed that (8x^{2} – 4x) quantity is the numerator

and that (4x – 2) quantity is the denominator.

Hard to tell what the problem is asking for.

I agree with your interpretation, Ron:

It’s a quadratic expression divided by a linear expression.

\(\large \frac{8x^2 - 4x} {4x – 2} \rightarrow 2x\) **This is implied by the exception** "*that x isnt equal to 1/2*"* *(sic).

**However, because it is written in ASCII SLOP it needs parenthetical operators to confirm this, else it can (and should) be strictly interpreted as**:

\(\large 8x^2 – 4*\frac{x}{4}* x – 2 \rightarrow 7x^2 -2 \)

**Both the forum’s calculator and Wolfram Alpha interpret the expression using Formal ASCII Mathematical Hierarchy. ** There are good reasons why ASCII Mathematical Hierarchy was formalized by mathematicians, engineers, and computer scientists. ASCII was developed to communicate with computers, not to teach math to humans; Eventually its use evolved into communicating with humans ...and genetically enhanced Chimps...and along with it came ambiguity because the composers or the readers **do not know the Mathematical Hierarchy.**

Of course computers can be programmed to make assumptions –ignoring hierarchy; so there are online algebra solvers that will simplify or solve it as a quadratic expression divided by a linear expression, without the use of parenthetical operators.
