Question

1-100a^2 pleasehelp me​

Answer 1

Answer:

factorisation :-

(1 + 10a) (1 - 10a)

Step-by-step explanation:

1 - 100a²

= 1×1 - 10×10a²

= 1² - (10a)²

= (1 + 10a) (1 - 10a)

[because a² - b² = (a+b)(a-b), here a = 1 and b = 10a]

Hence factorisation of 1 - 100a² =

(1 + 10a) (1 - 10a)

hope it helps.
