Answer:
16x^2 -24x +9
Step-by-step 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:
16x^2 - 9
Step-by-step 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.
