\huge\bold{\gray{\sf{Answer:}}}

 \bold{\red{=  > (2a÷3+b÷3)×(2a+3-b÷3)}}

 \bold{=  > ( \frac{2a}{3}  +  \frac{b}{3} ) \times (2a + 3 -  \frac{b}{3} )}

 \bold{=  >(  \frac{2a + b}{3} ) \times ( \frac{3(2a + 3) - b}{3} )}

 \bold{=  >(  \frac{2a + b}{3} ) \times ( \frac{6a + 9 - b}{3} )}

 \bold{=  >  \frac{(2a + b)(6a + 9 - b)}{3} }

 \bold{=  >  \frac{2a(6a + 9 - b) + b(6a + 9 - b)}{3}}

 \bold{=  >  \frac{12 {a}^{2} + 18a - 2ab + 6ab + ab -  {b}^{2}  }{3} }

 \bold{=  >  \frac{12 {a}^{2} + 18a + 4ab -  {b}^{2}  }{3}}

 \bold{\red{=  >  \frac{3a(4a + 6)+ b(4a - b)}{3} }}\mathbb{Answer}
