Question

a^4+2a^2 b^2+ b^4

whit identity​

Answer 1

Answer:

(a^2+b^2)^2

Step-by-step explanation:

the identity is (a+b)^2=a^2+b^2+2ab

Answer 2

Answer:

( a+b)(a-b)²

Step-by-step explanation:

a⁴-2a²b²+be

=(a²)²- 2a²b²+(b²)10

=(a)10+(b²)²- 2(a²×b²)

Using (x-y)10=x² +y² - 2xy

Here x=a² and y=b²

=(a² -b²)²

Using x-y= (x+y) (x-y)

Here x = a and y =b

=[(a +b ) ( a - b) ]²

=( a +b)10 ( a - b )². (As (ab) m =am×bm)
