Question

factorise (ax+by)²+(bx-ay)²

Answer 1

is it correct...??
if yes..
mark as brainliest
a²x²+b²y²+b²x²+a²y²
x²(a²+b²)y²(a²+b²)
(x²+y²)(a²+b²):ans....
:)

Answer 2

(ax^2 + by^2 + 2axby) + ( bx^2 + ay^2 - 2bxay)
= ax^2 + by^2 + 2axby + bx^2 + ay^2 - 2bxay
= ax^2 + by^2 + bx^2 + ay^2 ( + 2axby and - 2bxay gets cancelled)
= ax^2 + bx^2 + ay^2 + by^2
= x^2( a + b) + y^2 ( a + b)
= (x^2 + y^2 ) + (a+b)
hope this helps.
