x^2-0.36x20.36

Explanation:

Given: (x-0.6)(x+0.6)(x0.6)(x+0.6)

Use the fact that (a-b)(a+b)=a^2-b^2(ab)(a+b)=a2b2.

Here, a=x,b=0.6a=x,b=0.6.

=x^2-0.6^2=x20.62

=x^2-0.36=x20.36

(x-0.6)(x+0.6) = x^2 - 0.36 (x0.6)(x+0.6)=x20.36

Explanation:

Use the Difference of Squares Identity (a+b)(a-b) = a^2 - b^2(a+b)(ab)=a2b2

(x-0.6)(x+0.6) = x^2 - 0.36 (x0.6)(x+0.6)=x20.36
