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
