Question

(7x-6) (7x+6) standard form​

Answer 1

$\sf \: Answer$

$\sf(7x - 6)(7x + 6)$

Apply the identity as stated below :-

${\underline{\boxed{{\rm{\sf(a - b)(a + b) = \sf{a}^{2} - {b}^{2} }}}}}$

$\sf(7x - 6)(7x + 6) = (7x) {}^{2} - (6) {}^{2} \\ = \sf49 {x}^{2} - 36$

Therefore, 49 x² - 36 is the required standard form .

Hope it helps you to resolve your problem !!
