Answer:
3a(3)+2b(5)/15
9a+10b/15
Answer: [tex]\frac{9a^2}{25} + \frac{4ab}{5} + \frac{4b^2}{9}[/tex]
Step-by-step explanation:
[tex](\frac{3}{5} a + \frac{2}{3} b)^2[/tex]
=> [tex](\frac{3}{5}a)^2 + 2*\frac{3}{5} a*\frac{2}{3} b + (\frac{2}{3} b)^2[/tex] [since (a + b)² = a² + 2ab + b²]
=> [tex]\frac{9a^2}{25} + \frac{4ab}{5} + \frac{4b^2}{9}[/tex]
