Question

Im not sure what goes in the blanks i need answers please

Answer 1

Explanation:

Remember that

`(a + b) {}^(2) = {a}^(2) + 2ab + {b}^(2)`

So

`(2x) {}^(2) = 4 {x}^(2)`

So the first blank is 4

`2ab = 2(2x)(3) = 12x`

So the second blank is 12

And finally

`3 {}^(2) = 9`

So the final blank is 9.
