Question

Which term completes the product so that it is the difference of squares?
(-5x-3)(-5x+

Answer 1

The answer is (-5x - 3) (-5x + 3).

The difference of squares formula: (a + b) (a - b) = a^2 — b^2 can be applied to your given problem. If you use the FOIL method to verify whether it’s the correct answer:

(-5x - 3) (-5x + 3) = 25x^2 - 15x + 15x - 9
= 25x^2 - 9.
