Question

Use suitable identities to find the following products:

(a) (3x -6)(3x – 5)​

Answer 1

$\huge \star \; \bf \underbrace {ANSWER} \: \star$

‣ To Find :

$\textsf {The product}$

‣ Solution :

$\textsf {We know that,}$

$\fbox {\sf {(x + a) (x + b) = x² + x(a + b) + ab}}$

$\sf {Now,}$

→ $\sf {(3x - 6) (3x - 5)} \: \: \: \: \: \: \: [ \because \textsf {Using identity}]$

$\sf {= \; (3x)² + 3x[(-6) + (-5)] + (-6) × (-5)}$

$\sf {= \; 9x² + 3x[-11] + 30}$

$\sf {= \; 9x² - 33x + 30}$

$\implies \sf {\underline {Hence, \: the \: answer \: is \: 9x² - 33x + 30.}}$
