Question

Factorise. 49a square + 70ab + 25b square​

Answer 1

Hello mate here is your answer

49a^2 + 70ab + 25b^2 ( here " ^2 " represents square)

so let's factorise this expression.

49a^2+70ab+25b^2

(7a)^2+2(7a)(5b)+(5b)^2

By using

a^2+2ab+b^2= (a+b)^2

Therefore we get

(7a+5b)^2

Therefore , the factorised equation is (7a+5b)^2
