charle [14.2K]

Answer:

$\bf\pink{(a-12)\times (a+12)}$

Step-by-step explanation:

<h2><u>Given Expression</u> :-</h2>

$\bf\blue{a^{2} - 144}$

<h2><u>Steps to factorise</u> :-</h2>

$\longrightarrow\:\:\bf\red{a^{2} - 144}$

Write the number in the exponential form with an exponent of 2

$\longrightarrow\:\:\bf\orange{a^{2}-12^{2}}$

Using a²-b² = (a-b)(a+b), factor the expression.

$\longrightarrow\:\:\bf\purple{(a-12)\times (a+12)}$

(<u>Refer the attachment for graph representation</u>)

<h2><u>Graph Details</u> :-</h2>

$\bigstar\:\:\bf{y=a^{2}-144}$

$\rm{ Roots \:\:(-12,\:0)\:(12,\:0)}$

$\rm{Domain \:\:a \in {\mathbb{R}}}$

$\rm{Range \:\:y\in \bigg( -144,\:+\infty \bigg) }$

$\rm{Minimum \:\: (0,\:-144)}$

$\rm{Vertical\: Intercept\:\:(0,\:-144)}$
