Question

factorize: 49a^2-100b^2

Answer 1

Heya!

Here is yr answer.....

=> 49a² - 100b²

=> (7a)²-(10b)²

[ a² - b² = (a+b) (a-b) ]

=> (7a+10b) (7a-10b)

Hope it hlpz....

Answer 2

is the difference of 2 squares which says (a^2-b^2)=(a+b)(a-b) so you simplify what you have to ((7a)^2-(10b)^2) and use the difference of 2 squares to get (7a+10b)(7a-10b)
here is solved
49a^2-100b^2
=(7a)^2-(10b)^2 a^2-b^2=(a+b)(a-b)
=(7a+10b)(7a-10b)
