(3x + 4y)(3x – 4y)
Expanding the expression using the FOIL method, we get:
(3x + 4y)(3x – 4y) = 9x^2 – 12xy + 12xy – 16y^2
Simplifying, the middle terms cancel out and we are left with:
(3x + 4y)(3x – 4y) = 9x^2 – 16y^2
(3x + 4y)(3x – 4y) = 9x^2 – 12xy + 12xy – 16y^2
Simplifying, the middle terms cancel out and we are left with:
(3x + 4y)(3x – 4y) = 9x^2 – 16y^2
