Question

How do i factor x^4+16^2+64

Answer 1

\[x ^{4}+8x^{2}+8^{2}+\]

Answer 2

x4 + 8x2 +8x2 +64

Answer 3

take common
x2( x2+8) + 8 ( x2 + 8)

Answer 4

again take common
(x2+8)(x2+8)

Answer 5

or simply
(x2+8)^2

Answer 6

Okay i did all of that which im okay with. But then i get x^4+8x^2+64+8x^2.... So when i add up both 8x^2..... I come up with 16x^4..... When its suppose to be 16x^2..... Or do i not add the x^2's?

Answer 7

rearrange :
\[x ^{4} + 8x ^{2} + 8x ^{2}+ 64\]

Answer 8

now take common:
\[x ^{2} (x ^{2} + 8) + 8(x^{2} + 8)\]

Answer 9

\[x ^{2}+8 \]
is common again. so take common.

Answer 10

\[(x ^{2} + 8 ) (x ^{2} +8)\]
is your answer

Answer 11

Can x^4+13x^2+1 be factored out

Answer 12

No. Use quadratic formula for this one.
