Question

factorise 49x^2+70xy+25y^2​

Answer 1

Answer:

=(7x)^2 + 2*5x*7y + (5y) ^2

= (7x+5y)^2

so factor is (7x+5y )and (7x+5y)

hope you got your answer

Answer 2

Answer:

(7x+5y)^2

Step-by-step explanation:

49 is the square of 7

25 is the square of 5

I hope you have learn that formula

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

by using the following formula we get

(7x+5y)^2= (7x)^2 + 2×7x×5y + (5y)^2

=49x^2 + 70xy + 25y^2

I hope it helps you ...............
