Question

(3/4 a square + 3 b square ) × 4 ( a square - 2/3 b square)
​

Answer 1

Step-by-step explanation:

$(\frac{3}{4} a^{2} +3b^{2} )$ × $4(a^{2} - \frac{2}{3} b^2)$

$(\frac{3}{4} a^{2} +3b^{2} )$ × $(4a^{2} - \frac{8}{3} b^2)$

$3a^4 - 2a^2b^2+ 12a^2b^2 -8b^4$

$3a^4 + 10a^2b^2 -8b^4$

Answer 2

Answer:

Step-by-step explanation:

3a^4 +10b^4+ 10a^2b^2
