Question

expand
(За+2/b) (2a-3/b)​

Answer 1

Answer:

6a² + $\frac{4a}{b}$ + $\frac{9a}{b}$ - $\frac{6}{b^{2} }$  

Step-by-step explanation:

(За+2/b) (2a-3/b)​

= (3a * 2a) + ($\frac{2}{b} * 2a$) + ($\frac{3}{b} * 3a$) - ($\frac{2}{b} * \frac{3}{b}$)

= 6a² + $\frac{4a}{b}$ + $\frac{9a}{b}$ - $\frac{6}{b^{2} }$
