Simple...

you have $\frac{3}{8}$ and $\frac{2}{5}$

Just subtract...but first find a common denominator...

Use 40 as the common denominator...

$\frac{3}{8} * \frac{5}{5} = \frac{15}{40}$
and
$\frac{2}{5} * \frac{8}{8} = \frac{16}{40}$

So, subtract,

$\frac{15}{40}
-
 \frac{16}{40}$

= $- \frac{1}{40}$

Thus, your answer.

Answer:

x = +-sqrt(3) and they are the actual solutions

Step-by-step explanation:

x^2/ (2x-6) = 9/(6x-18)

get a common denominator of 6x-18

x^2/ (2x-6) * 3/3 = 9/(6x-18)

3x^2/ (6x-18) = 9/(6x-18)

since the denominators are the same, the numerators must be the same
