Answer 2

Hey mate, here is the AnsweR,

Question :

• $\bigstar \: \: \tt(k- \frac{ 2 }{ 3 } ) ^ { 2 }$

Required Solution :

Evaluate :

$\\ \bigstar \: \: \tt(k- \frac{ 2 }{ 3 } ) ^ { 2 }$

$\tt{ \underline{Use \: binomial \: theorem \: \left(a-b\right)^{2}=a^{2}-2ab+b^{2} \: to \: expand \: \left(k-\frac{2}{3}\right)^{2}.}}$

${\huge\star }\: \: \underline{ \boxed{: \implies{\tt{k^{2}-\frac{4}{3}k+\frac{4}{9}}}}} \: \: {\huge\star }$
