Answer 2

Hi ,

$\huge\red{\boxed{Answer}}$

$We \: \: are \: \: going \: \: to \: \: solve \: \: these \: \: questions \: using \: \: the \: \: identity:$

$\large{\boxed{ {a}^{2} - {b}^{2} = (a + b)(a - b) }}$

$(1)$

${94}^{2} - {6}^{2}$

$a = 94 \: \: b = 6 \\ (94 + 6)(94 - 6) \\ = (100)(88) \\ = 8800 \: \: \: \: \: \: \: \: \: \:$

_______________________________________________________________

$(2)$

${673}^{2} - {473}^{2}$

$a = 673 \: \: \: \: b = 473 \\ (673 + 473)(673 - 473) \\ = (1146)(200) \\ = 229200 \: \: \: \: \: \: \: \: \: \:$

$Hope \: \: this \: \: helps \: \: you \: !$
