​

Answer 1

Step-by-step explanation:

so here is your answer.

Answer 2

Answer:

$\frac{ {a}^{2} }{ {b}^{2} } + \frac{ {b}^{2} }{9} + \frac{2a}{3}$

Step-by-step explanation:

See,

this is a very simple question with a simple explaination.

CONCEPT:-

This question is of basic level class 8th and we just have to simplify the statement according to the law.

${(a + b)}^{2} = {a}^{2} + {b}^{2} + 2ab$

here,

$a = \frac{a}{b} ..b = \frac{b}{3}$

using this here we go,

a²+b²+2ab

$= > \frac{ {a}^{2} }{ {b}^{2} } + \frac{ {b}^{2} }{9} + \frac{2a}{3}$

This is the required a answer.

Still have queries do tell me.
