To multiply (7q - 5)(7q + 5), you can use the distributive property or the FOIL method. FOIL stands for First, Outer, Inner, Last, which helps organize the multiplication process.

First, multiply the first terms of each binomial: (7q)(7q) = 49q^2. Outer, multiply the outer terms: (7q)(5) = 35q. Inner, multiply the inner terms: (-5)(7q) = -35q. Last, multiply the last terms: (-5)(5) = -25.

Combine the like terms: 35q - 35q = 0.

So, the expression simplifies to 49q^2 - 25.
