For this case we must find the product of [tex](2x + 3) (2x-3)[/tex], for this, we must apply the distributive property, which by definition establishes that:
[tex](a + b) (c + d) = ac + ad + bc + bd[/tex]
So:
[tex](2x + 3) (2x-3) = (2x) ^ 2 + (2x) (- 3) + (3) (2x) + (3) (- 3)[/tex]
considering that[tex]+ * - = -[/tex]
[tex](2x + 3) (2x-3) = 4x ^ 2-6x + 6x-9\\(2x + 3) (2x-3) = 4x ^ 2-9[/tex]
Answer:
Option A
