The product of the given expression is:

16m^4-25

Step-by-step explanation:

We are asked to find the product if two quadratic expressions which are given in terms of variable "m".

The expression is given by:

(4m^2-5)(4m^2+5)

We could observe that the expression is given in the form of:

(a-b)(a+b) which is simplified by the rule:

(a-b)(a+b)=a^2-b^2------------(1)

Here $a=4m^2\ and\ b=5$

Hence, by using the formula (1) we get:

$(4m^2-5)(4m^2+5)=(4m^2)^2-5^2\\\\\\(4m^2-5)(4m^2+5)=16m^4-25$

The product is:

16m^4-25
