Question

plzzz factorize it........​

Answer 1

Answer: A

Step-by-step explanation:

The answer is A.

4x^4+16

=4(x^4+4)                                     Find roots of numbers in bracket.

=4(x²+2)(x²-2)

If you are ever in an exam and are unable to do questions like these, then have a look at the answers, and multiply them. Whichever answer multiplies to give the expression to be factorized(4x^4+16 in this case) will be the answer. When we multiply 4(x²+2)(x²-2) we get 4x^4+16, so this answer is correct. Hope this helps, thanks.
