Question

Find the product........................................

Answer 1

For this case we must find the product of
`(2x + 3) (2x-3)`, for this, we must apply the distributive property, which by definition establishes that:

`(a + b) (c + d) = ac + ad + bc + bd`

So:

`(2x + 3) (2x-3) = (2x) ^ 2 + (2x) (- 3) + (3) (2x) + (3) (- 3)`

considering that
`+ * - = -`

`(2x + 3) (2x-3) = 4x ^ 2-6x + 6x-9\\(2x + 3) (2x-3) = 4x ^ 2-9`

Answer:

Option A
