Answer:
Option A is correct.
[tex]49x^2+ 9[/tex]
Step-by-step explanation:
Find the correct product of [tex](7x-3)(7x+3)[/tex]
Distributive property states that lets you multiply a sum by multiplying each addend separately and then add the products.
i.e, [tex]a\cdot (b+c) = a\cdot b+ a\cdot c[/tex]
The product for the following :
[tex](7x-3)(7x+3)[/tex]
Apply distributive property;
[tex]7x(7x+3) -3(7x+3)[/tex]
[tex]49x^2+21x -21x + 9[/tex]
Combine like terms;
[tex]49x^2+ 9[/tex]
Therefore, the product of [tex](7x-3)(7x+3)[/tex] is, [tex]49x^2+ 9[/tex]
