For any Real value of x

300x2=103|x|

If we know that x0 then this simplifies further to:

103x

Explanation:

Note that for any non-zero value of x, x2 has two square roots, namely x and x.

The expression x2 denotes the principal square root, which is the non-negative one.

Hence: x2=|x|

So we find:

300x2=1023x2=1023x2=103|x|

If we know that x0 then |x|=x and this simplifies further to 103x
