Question

(2a+3b)^2 + (2a – 3b)^2​

Answer 1

Answer:

4a^2+9b^2+12ab+4a^2+9b^2-12ab

8a^2+18b^2....

2(4a^2+9b^2)

(a+b)^2=a^2+b^2+2ab

(a-b)^2=a^2+b^2-2ab

Answer 2

$\huge{\red{\underline{\underline{\mathcal{Solution:-}}}}}$

(2a + 3b)² + (2a - 3b)²

4a² + 12ab + 9b² + 4a² - 12ab + 9b²

4a² + 4a² + 9b² + 9b²

8a² + 18b²

8(a² + b²)

$\huge{\boxed{\boxed{\pink{8({a}^{2} + {b}^{2})}}}}$
