Question

multiply the binomials
(3/4a² +3b²)×4(a²-2/3)​

Answer 1

Step-by-step explanation:

the formula of a+b a-b is a²-b²

so as for question

(3a²/4+3b²)×4(a²-8/3). = (3a²/4+3b²)×(4a²-24/3)

*first - into both the a with each other

3a²/4×4a² = 12a²/4a² it can be cancel by the table of 4 than it will be 3a²

*second step - multiply both the b

which will be 3b²×24/3 = 24b²

now apply the formula

a²-b² = 3a²-24b²
