Question

169b⁴-100

Factorise it​

Answer 1

Answer:

☆(13b²+10)(13b²-10)☆

Step-by-step explanation:

the given polynomial is in the form of a² -b²

we can write 169b⁴ as (13b²)²

we an write 100 as 10²

so the given polynomial is (13b²)²-10²

we know that a²-b²=(a+b)(a-b)

here a=13b² and b=10

so the answer is ☆(13b²+10)(13b²-10)☆
