Required Answer:-
Given To Factorise:
- x² - 25b²
Solution:
We know that,
➡ a² - b² = (a + b)(a - b)
Using this identity, we can factorise it.
x² - 25b² can be written as,
= (x)² - (5b)²
= (x + 5b)(x - 5b) which is the factorised form of the polynomial.
If you don't know this identity, there is another approach of solving. Here is it.
x² - 25b² can be written as,
= x² - 5bx + 5bx - 25b² (Add and subtract)
= x(x - 5b) + 5b(x - 5b)
= (x + 5b)(x - 5b) which is the factorised form.
★ Hence, the factorised form of the polynomial is (x + 5b)(x - 5b)
Answer:
- The factorised form of the polynomial is (x + 5b)(x - 5b)
