Question

Phân tích đa thức thành nhân tử
4x^2-4y^2

Answer 1

4x² - 4y²

= (2x)² - (2y)²

= (2x - 2y)(2x + 2y)

Answer 2

(2x - 2y)(2x + 2y)

Answer 3

4x²-4y²=4.(x²-y²)=4.(x-y).(x+y)

Answer 4

\(4x^2-4y^2=4\left(x^2-y^2\right)=4\left(x-y\right)\left(x+y\right)\)

Answer 5

C₂:

4x² - 4y²

= 4(x² - y²)

= 4(x - y)(x + y)

Answer 6

\(4x^2-4y^2=4\left(x-y\right)\left(x+y\right)\)
