Question

find the product of (x+2)×(x-2) using identity​

Answer 1

Answer:

its simple to answer (x²+x²/2)²

let x²=a. and x²/2= b

(a+b)²=a²+b²+2ab

=(x²)²+(x²/2)²+2x²*x²/2

= (x²)²+(x²)²/4+(x²)²

=2(x²)²+(x²)²/4

=(8(x²)²+(x²)²)/4

=9(x²)²/4

another method:

= (x²+x²/2)²

=((2x²+x²)/2)²

=(3(x²))²/4

=9(x²)²/4
