simplify the expression below and state the value of m for which the simplified expression is not defined 2m² + m - 15/ m² - 9

Answer:

The simplified expression is: $\frac{2m-5}{m-3}$

The simplified expression is undefined for m=3

Explanation:

The given expression is:

$\frac{2m^2+m-15}{m^2-9}$

The numerator can be siplified by using factorization and denominator will be simplified using the formula

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

So,

$= \frac{2m^2+6m-5m-15}{(m)^2-(3)^2}\\=\frac{2m(m+3)-5(m+3)}{(m-3)(m+3)}\\=\frac{(2m-5)(m+3)}{(m-3)(m+3)}\\=\frac{2m-5}{m-3}$

A fraction is undefined when the denominator is zero. In order to find the value of m on which the simplified fraction will be undefined we will put denominator equal to zero.

So,

$m-3 = 0 => m = 3$

Hence,

The simplified expression is: $\frac{2m-5}{m-3}$

The simplified expression is undefined for m=3

Editing codes in the Chrome DevTools console does not affect the source code of the website hosted on a server, it just provides instant editing functions for troubleshooting or website enhancement.

Therefore, refreshing the page, re-loads the website again from its database which will show the unedited website. In our scenario, after refreshing the page, all the deleted DIV that contains all the authentication will reappear again.
