Respuesta :

A2 + B2 = (A + Bi)(A – Bi) so the answer is (x + 4i)(x - 4i)

Answer:

The product of factors irreducible over the reals are [tex]x^2+16=(x+4i)(x-4i)[/tex]

Step-by-step explanation:

Given : Quadratic form  [tex]x^2+16[/tex]

To find : Write the quadratic as a product of factors irreducible over the reals?

Solution :

To find the product first we have to find the roots of the quadratic.

[tex]x^2+16=0[/tex]            

[tex]x^2=-16[/tex]  

Root both side,

[tex]\sqrt{x^2}=\sqrt{-16}[/tex]    

[tex]x=\pm 4i[/tex]  

So,The factors of the quadratic equation is [tex](x+4i)(x-4i)[/tex] in the form of complex number.

Therefore, The product of factors irreducible over the reals are [tex]x^2+16=(x+4i)(x-4i)[/tex]
