Answer 1

((3/4)*(a)^2 + 3(b)^2) * 4((a)^2 - (2/3)(b)^2)

= 4*(a)^2* ((3/4)*(a)^2 + 3(b)^2) - 4*(2/3)(b)^2)*((3/4)*(a)^2 + 3(b)^2)

= 4*(a)^2* (3/4)*(a)^2 + 4*(a)^2*3(b)^2 - 4*(2/3)(b)^2)*(3/4)*(a)^2 - 4*(2/3)(b)^2)* 3(b)^2

= 3*(a)^4 + 12*(a)^2*(b)^2 - 2*(a)^2*(b)^2 - 8*(b)^4

= 3*(a)^4 + 10*(a)^2*(b)^2 - 8*(b)^4 ——> Answer
