Answer
makes sense.
Work Step by Step
Think about the product $(2x+3y)(2x-3y)$.
If we use FOIL, it will look like this:
$(2x+3y)(2x-3y)=(2x)(2x)-(2x)(3y)+(3y)(2x)-(3y)(3y)=4x^2-9y^2$.
However, when using the formula $(A+B)(A-B)=A^2-B^2$, we have
$(2x+3y)(2x-3y)=(2x)^2-(3y)^2=4x^2-9y^2$.
Thus, the statement makes sense.
