What is the factored form of the expression over the complex numbers?

16x^2+9y^2



(4x+3iy)(4x−3iy)

(4x+3y)(4x−3y)

(4x+3iy)(4x+3iy)

(4x−3iy)(4x−3iy)

Respuesta :

the first answer is correct


[tex]16 {x}^{2} + 9 {y}^{2} = (4x + 3y)(4x - 4y)[/tex]
No "i" is needed unless less you take the square root of a negative number.
