Question

what is the answer if you factor out 25x^4+16x^2 y^2+4Y^4

Answer 1

Is that \[25x^4+16x^2y^2+4y^4\]?

Answer 2

its 16x to the power of two then y to the power of 2

Answer 3

\[ \left(5 x^2-2 x y+2 y^2\right) \left(5 x^2+2 x y+2 y^2\right) \]

Answer 4

\[(5 x^2 - 2 x y + 2 y^2) (5 x^2 + 2 x y + 2 y^2)\]

Answer 5

may i ask how did you derive from thet answer?

Answer 6

If you let \[a=x^2\] and\[b=y^2\] then you would have:
\[25a^2+16ab+4b^2\]
Take a good look at the constants, they are actually very much factorable.

Answer 7

thanks :)

Answer 8

Sure, no problem.
