Find the product.
(4m^2-5)(4m^2+4)
To find the product, we need to use the distributive property and multiply each term in the first expression by each term in the second expression.
The first term of the product will be:
(4m^2)(4m^2) = 16m^4
The second term of the product will be:
(4m^2)(4) = 16m^2
The third term of the product will be:
(-5)(4m^2) = -20m^2
The fourth term of the product will be:
(-5)(4) = -20
Putting it all together, the product is:
16m^4 + 16m^2 - 20m^2 - 20
Combining like terms gives us:
16m^4 - 4m^2 - 20.
