Question

(3/4a² + 3b²) 4(a² - 2/3 b²)​

Answer 1

Step-by-step explanation:

(3/4 a² + 3b²) and 4(a² – 2/3 b²)

(3/4 a² + 3b²) x 4( a² – 2/3 b²)

= (3/4 a² + 3b²) x (4a² – 8/3 b²)

= 3/4 a² x (4a² – 8/3 b²) + 3b² x (4a² – 8/3 b²)

= (3/4 a² x 4a²) – (3/4 a² x 8/3 b²) + (3b² x 4a²) – (3b² x 8/3 b²)

= 3a4 – 2a²b² + 12 a²b² – 8b4

(3/4 a² + 3b²) x 4( a² – 2/3 b²) = 3a4 + 10a²b² – 8b
