Question

factroise 16 - x²- 2xy - y²​

Answer 1

Step-by-step explanation:

Given, 16−x

2

−2xy−y

2

=4

2

−[x

2

+2xy+y

2

]

=4

2

−(x+y)

2

By using a

2

−b

2

=(a+b)(a−b)

∴4

2

−(x+y)

2

=(4+x+y)(4−x−y)

Answer 2

Answer:

1. hope this helps...

16-x^2-2xy-y^2

(4)^2 - ( x^2 + 2xy + y^2)

(4)^2-(x+y)^2

a^2-b^2=(a+b)(a-b)

(4)^2 - (x-y)^2= (4+x+y)(4-x-y)
