Answer 1

16x^2 -24x +9

Explanation:

4x x 4x = 16x^2

4x x -3 = -12x

4x x -3 = -12x

-3 x -3 = +9

When all values are put together, they will form:

16x^2 -12x -12x +9

Once simplified, the equation will be:

16^2 -24x +9

Answer 2

16x^2 - 9

Explanation:

It is possible to solve this without actually multiplying.

There is a rule: (a+b)(a-b) = a^2 - b^2

So, when this is applied here:

(4x-3) (4x + 3) = 16x^2 - 9

All you had to do was 4x^2 and 3^2

Hope this helps.
