To know the product of (4x-3)(4x+3),
First multiply 4x by 4x, which will results in
Then multiply 4x by -3 and is equal to -12x.
Then multiply 4x by 3, that is equal to 12x.
Then multiply the last term, +3 times -3 and is equal to -9.
Lastly arranged: (
. You can cancel -12x and 12x since when you add them it will give you 0.
So, the product of (4x-3)(4x+3)=
