  • Step-by-step explanation:

First convert x power 4 as (x power 2 ) power 2 and 25 as 5 square.

Then make x square as 10x square minus 9x square.

Then ,shift 9x square to last.

Now you get like identity I , (x)^{2} + 2xy + {y}^{2} = (x + y) ^(2) .

That is, (x square plus 5 )power 2 minus 9x square.

9x square is actually (3x) power 2.

Now it is (x square plus 5 )power 2 minus (3x) square.

Then , (x square plus 5 minus 3x) (x square plus 5 plus 3x) is the answer.
