Question

Multiply the binomials `(3/4 a^2 + 3b^2) and 4(a^2 - 2/3 b^2)`

Solution

`(3/4 a^2+ 3b^2) xx [4(a^2 - 2/3 b^2)] = (3/4 a^2 + 3b^2) xx (4a^2 - 8/3 b^2)`

= `3/4 a^2 xx (4a^2 - 8/3 b^2) + 3b^2 xx (4a^2 - 8/3 b^2)`

= `3a^4 - 2a^2b^2 + 12b^2a^2 - 8b^4`

`= 3a^4 + 10a^2b^2 - 8b^4`

  Is there an error in this question or solution?
