Answer:

double quotes

Explanation:

In general all string literals are surrounded by double quotes(" ").

EX: string simple="This is simple string";

Each character in the string literal occupies 1 byte memory. All strings are terminated by '\0' character. It indicates the end of the string. If it is character

literal then we can enclose it in '' single quotes. Each character in the string is represented in the form of ACII value(ASCII stands for American Standard Code for Information Interchange).

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,

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