Answer 1

$\large\bf\underbrace{\red{SOLUTION:-}}$

CONCEPT :-

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

CALCULATION :-

ʘ Here,

• a = x²
• b = 2/3

╭☞ So,

$( {x}^{2} + \frac{2}{3} ) \: ( {x}^{2} - \frac{2}{3} ) \\ \\ = { ({x}^{2}) }^{2} - {( \frac{2}{3} )}^{2} \\ \\ = {x}^{4} - \frac{4}{9}$
