Question

4x2+28xy+49y2 factorise answer me quick​

Answer 1

Factor = 4x^2+28xy+49y^2

Rewrite 4x^2 as (2x)*2

(2x)*2+28xy+49y*2

Rewrite 49y*2 as (7y)*2

(2x)*2+28xy+(7y)*2

Check the middle term by multiplying

2ab and compare this result with the middle term in the original expression.

2ab=2. (2x). 7y

Simplify

2ab= 28xy

Factor using the perfect square trinomial rule

a*2+2ab+b*2

= (a+b)*2

where a=2x and b=7y

So the answer is

(2x+7y)*2

Hope it helps☺️
