The sum of a and b will be the coefficient of the x term of the trinomial. This can be seen below.

(x + a)(x + b)
= x² + bx + ax + ab
= x² + (a+b)x + ab

x is being multiplied by both a and b individually and the products are being added, so sum of a and b appears as the coefficient of x term.

Thus the answer to this question is option C

Step-by-step explanation:

<h3>to understand the solving steps</h3><h3>you need to know about</h3>

$\sqrt{ \frac{x}{y} } < = > \frac{ \sqrt{x} }{ \sqrt{y} } \\ and \: \\ \sqrt{x} \times \sqrt{y} = \sqrt{xy}$
PEMDAS

let's solve:

$a) \sqrt{ \frac{9}{25} }$

$\frac{ \sqrt{9} }{ \sqrt{25} }$

$\frac{3}{5}$

$b) \frac{ \sqrt{12} }{ \sqrt{3} }$

$\frac{ \sqrt{12} }{ \sqrt{3} } \times \frac{ \sqrt{3} }{ \sqrt{3} }$

$\frac{ \sqrt{12 \times 3} }{ (\sqrt{3} )^{2} }$

$\frac{ \sqrt{36} }{3}$

$\frac{6}{3}$

$2$

$c) \frac{ \sqrt{15} }{ \sqrt{3} }$

$\sqrt{5}$
