Answer:
Step-by-step explanation:
(2x-4) (2x+4) = (2x)² - 4²
= (2x)² - 4² (simplify)
= 4x² -16
Answer:4x^2-16
EXPLANATION(:
(2x-4)(2x+4)
Simplify
Distribute
(2x-4)(2x+4)
2x(2x+4)-4(2x+4)
Distribute
2x(2x+4)-4(2x+4)
4x^2+8x-4(2x+4)
Distribute
4x^2+8x-4(2x+4)}
4x^2+8x{-8x-16}
Combine like terms
4x^2+8x-8x-16
4x^2-16
Answer:
4x^2-16
