Question

factorise the sum in the picture

Answer 1

Given⤵️

factorise :25x⁴-10x²y²+y⁴

✯solution✯

25x⁴-10x²y²+y⁴

(5x²)²-2×5x²×y²+(y²)²

=(5x²-y²)²(solution)

we worked out the factorization using identities

in this case we used :-

(a-b)²........(2)

more information ☞

there are six methods of factorization .these are

1)greatest common factor

2)grouping method

3)sum or difference in two cubes

4)difference between two squares method

5)general trinomials

6)trinomial method
